From design, components, working principle to specifications, you will find all information you’re looking for right here.

Let’s dive right in.

What is a Flanged Globe Valve?

This is a device that uses linear motion to regulate the flow in and connect valves in a pipeline system.

Flanged Globe Valve

What is a Flanged Globe Valve used for?

One can use the device to start, regulate, and stop the flow of fluid.

The flow disk can be out of the flow path or close the flow path entirely.

Also, the discs will move perpendicularly to the seat when opening and closing the flanged globe valve.

The motion will create annular space between the seat ring that closes gradually when you close the disc.

This makes a flanged globe valve have a suitable throttling capability which is vital for regulating the flow of fluids.

Besides, it has minimal leakage than that of a gate valve.

This is because the seat rings and discs have a good angle of contact that forms a tight seal.

What are the Typical Applications of Flanged Glove Valves?

There are several industries that use flanged globe valves.

They are important in systems where you need to control flow and prevent leakages.

The common Uses of flanged glove valve include:

What are the Disadvantages of Flanged Globe Valve?

The main shortcomings of flanged globe valve consist of:

• It is more expensive than a gate valve system.
• Also, it is heavy when you compare it with other valves that have the same pressure ratings.
• The large valve will need a lot of power to open and this creates noise when it is in high pressure operation modes.
• Besides, pulsation and impact can destroy the internal trim parts when operating in a high-pressure line.
• A high head loss due to obstructions and discontinuities in the path of flow.
• High head loss comes from two or more right-angle turns of the flow of fluid in the valves.

What are Flanged Globe Valve Dimensions?

The dimensions vary from one flanged globe valve to the next.T

hese dimensions are dependent on your application needs, and can range between 2 inches to 36 inches.

How does a Flanged Globe Valve Work?

Flanged Globe Valve Working Principle

From the external point of view, a flanged globe valve has a handwheel, body, and a bonnet.

The bonnet houses the stem, and when you turn the handwheel, the stem will screw upwards and downwards within the bonnet.

Also, the end part of the stem has small components known as disks or plugs.

These parts can be non-metallic or metallic in nature and can have varying shapes depending on your needs.

A seat is within the globe-shaped body and divides the body into two parts or chambers.

Also, it has a hole which allows fluid to pass through.

When you open the valve, the fluid will flow up via the opening into the seat.

To shut it off, you can screw the stem down until you block the seat’s opening using the disk.

Also, a flanged globe valve can modulate the flow of fluid.

It does this when you partially open it and adjust the flow without stopping it.

A pressure loss can happen in the system as the liquid encounters some resistance like gravity, friction, and turbulence.

Pressure loss and turbulence happens as the flanged globe valve forces the fluid to change direction of flow.

The amount of loss depends on friction with the system or velocity of the fluid.

What is the Material of Construction of Body and Trim for Flanged Globe Valves?

The material that constructs this system can be:

• Metallic alloys
• Synthetic materials
• Carbon steel
• Hastelloy
• Monel
• Inconel
• Cast iron
• Bronze or brass
• Ductile iron
• Cobalt-based allows
• Cast steel
• Alloy steel
• Forged stainless steel
• Cast aluminum bronze

What is the Difference between Flanged Globe Valve and Flanged Gate Valve?

Here is the comparison between flanged Globe Valve vs. Flanged Gate Valve:

Flanged Globe Valve

It has a complex construction as the major parts are inside the body cavity of the system.

Also, it has the capacity to have a high pressure drop.

The flanged globe valve is unidirectional and one uses it to control the flow of fluids.

Besides, the disk of the flanged globe valve moves in a parallel direction to the flow medium.

It will also offer a high resistance to the flow of fluids.

The weight of this system is greater than that of flanged gate valve even though they are of similar size and rating.

Due to its complex design, a flanged globe valve is expensive than a flanged gate valve.

Besides, these systems are suitable for applications which are 12 inches in size or below.

Flanged Gate Valve

This system has a simple construction with the major parts on the top part of the body.

It also offers a low pressure drop.

The flanged gate valve has a multi-directional valve and is suitable for isolation of fluids.

Gate valves in this system will move in a perpendicular motion to the flow of the fluid.

This system will offer a small resistance the flow of fluid.

Also, it is light weight than a flanged globe valve of the same size and rating.

Its simple design makes this system affordable.

Besides, you can use a flanged gate valve in larger applications.

Can Flanged Globe Valve be used for Isolation?

One may use this system for isolation and throttling applications.

However, they feature a high pressure drop than other straight valves like flanged gate valves.

It is possible to use it for isolation in scenarios where a drop in pressure in the valve is less of a controlling factor.

What is the Symbol for Flanged Globe Valve?

Flanged Globe Valve Symbol

There are different valve symbols that one can use in P&ID.

Several kinds of valves will assist in piping processes and they all have different symbols.

This makes reading P&ID of valves a difficult task but with practice, one can easily remember these symbols.

Two types of valve symbols exist, that is, generic symbols and a symbol that has a modifier.

Generic symbol will illustrate presence of a valve in the line but does not have information about the specifics of the valve.

On the other hand, a symbol with a modifier will illustrate the exact valve that you are using in the pipeline.

For a flanged globe valve, one will add a small dark circle between the triangles.

There will be two triangles facing each other with the pointy ends touching, and small dark circle where the two triangles meet.

Also, the opposite ends of the triangles will have a dark straight line to indicate it is flanged.

Do Flanged Globe Valves have Flow Direction?

You can install globe and angle valves for low temperature applications.

This makes the pressure to be under the disk and assists for an easy operation.

It also protects the packing and will minimize a specific amount of erosive action to the faces of the seat and disks.

In high pressure applications, one will install the flanged globe valve to make the pressure happen above the disks.

Otherwise, the stem contracts when it cools and will lift the disk off the seat and cause leakages.

Is Flanged Globe Valve Unidirectional?

Yes, a flanged globe valve is unidirectional.This means the fluid medium will flow in one direction.

On the contrary, a bidirectional valve means that you can use any side for upstream or downstream flow.

How can you Know if a Flanged Globe Valve is Open or Closed?

When the top handle is in a parallel direction to the valve, it is open.

On the other hand, when the handle is perpendicular to the top part, the valve is closed.

What are the Different Types of Flanged Globe Valve?

One can find three types of flanged globe valves namely:

Standard Pattern Flanged Globe Valve

This is also the Z- pattern, T- pattern, or Tee pattern, and the most common type of flanged globe valve.

The horizontal placement of the seat makes the stem and the disk to move perpendicularly to the direction of fluid flow.

Also, it gives the most resistance to flow among all the available types of flanged globe valve.

This is because it offers a tortuous flow passage to the fluid.

Besides, it offers the highest pressure drop and the smallest coefficient of flow.

They are suitable for extreme throttling applications like the bypass lines that are around control valves.

Also, one can use this type in applications that a drop in pressure is not a concern, but only the throttling needs.

Angle Pattern Flanged Globe Valve

This is a modification on the basic pattern flanged globe valve.

The ends of an angle pattern are at an angle of 90 degrees.

This means the flow of fluid happens at 90 degrees turn.

Besides, this pattern has a lower coefficient to flow than in oblique pattern flanged globe valves.

Also, they are suitable in applications that have a series of pulsating flows.

This is because they can handle slugging effects that happen on this kind of flow.

There are two benefits if you mount an angle pattern flanged globe valve close to the bend of a pipe.

First, the angle pattern design offers minimal resistance to flow than the standard pattern design.

Also, you will use less amounts of pipe joints and it will save the pipe elbow.

Oblique Pattern Flanged Globe Valve

This is an alternative to the high pressure drops that a flanged globe valve possesses.

Also, it will lower the resistance to flow to the minimum due to its design.

The seat and the stem are averagely 45 degrees to one another.

This offers a much straighter path of flow and the least flow resistance when you open it fully.

Besides, you can use this pattern when you fully open it, and for a long duration with no extreme erosion.

This design is suitable for throttling on seasonal or startup applications.

Also, one can rod through it to eliminate debris if you use it in drain lines which are usually not open.

What are the Parts of a Flanged Globe Valve?

There are several parts and components that make up a flanged globe valve, which include:

Flanged Globe Valve Parts

• Valve Body

This is the entire body of the flanged globe valve.

• Wheel and Nut

It is for the manual operation of the valve system.

• Gland Packing

It will inhibit leakage of fluid from the stem.

• Stem

This part will join the disk and the valve actuator.

• Yoke Sleeve

It will house the stem, gland and flange, and the gland bolts.

• Bonnet

It is the outer part of the valve.

• Handwheel

This is a wheel that the operator can use to turn the stem.

• Valve or Disk

This is a physical and movable barrier that moves up and down and regulates the flow of fluid.

• Disc Seat

This part tightly presses on the seat to inhibit fluid from flowing.

Other parts you can find in a flanged globe valve are:

• Pressure seal gasket
• Seat ring
• Gland flange and bushing
• Bonnet bolting
• Gland follower
• Body seat ring
• Handwheel and yoke nuts

How do you Install a Flanged Globe Valve?

A flanged globe valve is unidirectional and will take the flow of fluid in one direction under the disks.

Also, there is an arrow of this direction of flow cast within the body.

You can locate the arrow by checking one valve end to confirm if you are seeing the underside or over the seat.

Also, it is advisable to install it vertically in situations where the handwheel will be at the top part of the valve.

This makes it not have any premature wear and tear within the valve.

Here are the steps on how to install this unit:

• Eliminate any debris or packing away from the valve.
• Also, ensure the interior of the flanged globe valve has no water or moisture. This is because it can expand when you apply heat during startup.
• Make sure to support the valve. This is due to damage possibility when you use it for a long period without support whilst using a pipe clamping.
• Ensure there is enough space to operate the flanged globe valve.
• Perform an entire dry cycle when the valve is closed to open and then repeat the process.
• After that, Tighten the flange bolts in a diagonal fashion.
• Then, slowly raise the inside pressure to ensure all flanges and bolts are in a correct position.
• Also, check the valve to make sure it has a complete seal.
• After that, raise the interior pressure to an operating level and monitor the system once again.

How do you Choose Flanged Globe Valve for an On-Off Isolation Service?

Make sure to select a suitable design since maintaining a tight seal from the force of the fluid pushing upwards is difficult.

Also, the stem distance between open and closed position is short thus minimal wear and tear will occur.

This makes it easy to repair.

What are the Main Flanged Globe Disc Designs?

There main types of disc designs in a flanged globe design:

Flanged Globe Valve Disc Designs

Conventional Disc

This is also known as the ball disc.

It is the earliest design of the disc and the seat configuration.

Also, it has a ball-shaped metal disc that has a short taper that fits on the flat-surfaced seat within the body.

Besides, this design is affordable and common in low pressure applications where extreme throttling is not a necessity.

The basic use it to stop and start fluid flow, even though it has a capability of throttling flow.

It is advisable to use a conventional or ball disc when it is entirely open or closed.

This is because the taper can undergo extreme erosion together with wire drawing.

When the surface of the seat and disc has minimal damages, one can easily reground it.

Composition Disc

This design will use a sturdy, non-metallic ring insertion on the disc.

The insert ring will create a tight closure.

These designs are suitable for steam and hot water usages.

They also are erosion resistant and offer resilience to solid particles near it without destroying the valves.

Besides, one can replace composition discs.

Conventional discs offer an improvement to ball discs even though they are unsuitable for throttling applications.

Several kinds of composition discs are available to make this type usable for several applications.

Also, it is easy to repair, replace, and needs minimal power to form a tight seat.

Besides, tiny particles will not damage it since they will stick in the soft disc.

Plug Type Disc

This is the best design for difficult and throttling services.

A cone will provide a broad seating surface as the disc is a long and tapered metallic plug.

It offers full flow in moments when valves are wide open.

Also, foreign material or wire drawing will not affect this design.

Its construction makes it possible to replace and repair when need arises.

What is Flanged Globe Valve Disc- Stem Configuration?

The stem of a flanged globe valve may rotate when you are lowering or raising the disc.

Similarly, it may not rotate when performing this task.

The mode of operation has bearings on the designs of the connection between the disc and stem.

Besides, the disc can make the stem to rotate or the disc can move independently on the stem.

Here are the available disc – stem configurations for flanged globe valve:

• Rotating stem that has an integral disc.
• Non-rotating stem that has an integral disc.
• Rotating stem with a non-integral disc.
• Non-rotating stem with non-integral discs.

How do Flanged Bonnet Joints compare to Bolted Joints?

It is possible to spread the tightening force over several bolts in a flanged bonnet joint.

Nevertheless, this is not possible with bolted joints.

Also, this capability makes flanged bonnet joints suitable for any size of valve and operational pressure.

However, an increase in operating pressure and size of the valve makes the flanged bonnet joints bulky and heavy.

Also, in temperatures over 350 degrees Celsius, creep relaxation will lower the bolt load of flanged bonnet joints.

Bolted joints are a cheaper option.

However, the torque you need to tighten the joint is large for valves with higher sizes.

Also, bolted joints are suitable for sizes of valves that are less than NPS 3.

Are there Size Restrictions when selecting Flanged Globe Valves?

There are no size restrictions since you can spread the tightening force over several bolts.

Flanged Globe Valve

What is Flanged Globe Valve Differential Pressure Limit?

The maximum differential pressure along the flanged globe valve should not be more than 20% the maximum upstream pressure or 200 psi.

Flanged globe valves with special trims can exceed these differential pressure limits.

How do you Maintain Flanged Globe Valves?

Maintaining this equipment makes sure it operates optimally and meets your operational needs.

Here are some maintenance practices you can apply:

• Inspect the valve regularly to ensure all parts are in good working condition.
• Inspect the glands to ensure there are no tear, wear, or leakages.
• Cycle the flanged globe valve if you are not using it regularly to prevent the disc from embedding on the seat.
• Lubricate the cross bar and the spindle to reduce friction which will cause tear and wear.
• If the packing needs adjustments, you can tighten the gland bolts and make sure not to over tighten them.
• replace the gland packing if you notice leakages on the bolts.

What is Flanged Globe Valves Pressure Class Rating?

They are:

• ANSI B16.1 Cl. 125 has a pressure rating of 175 to 150 psi.
• ANSI B16.1 Cl. 250 has a pressure rating of 300 to 400psi.
• ANSI B16.5 Cl. 150 has a pressure rating of 275 psi.
• AWWA Cl. B has a pressure rating of 86 psi.
• AWWA Cl. D has a pressure rating of 150 to 175 psi.
• AWWA Cl. E has a pressure rating of 275 psi.
• AWWA Cl. F has a pressure rating of 300psi.

Can you use Flanged Globe Valve as a Control Valve?

Yes, you can use it to control the flow of fluids.

What is meant by Upstream/Downstream Side of Flanged Globe Valve?

Upstream side means it regulates the inlet pressure by opening in proportion to the inlet pressure.

Downstream side means it regulates the outlet pressure to a suitable point, irrespective of the flow variation and inlet pressure.

What is the Difference between Flanged Globe Valve and Flanged Ball Valve?

Flanged globe valves have a high pressure drop than flanged ball valve.

The flanged ball valve uses balls that close across flow of fluid while that of flanged globe valve operates against the flow.

Moreover, Flanged globe valves have a linear motion of valves while flanged ball valves have a rotary motion of valves.

The level of control is better in flanged globe valve than flanged ball valves.

It is slow to operate a flanged globe valve while easy to quickly shut off a flanged ball valve.

Also, flanged globe valves are affordable than flanged ball valves as they have a simple design.
