Unique Features of Kinvalve Socket Welded Ball Valve

Kinvalve offers you the Socket Welded Ball Valve, also known as socket weld or SW Ball Valve, in high quality, engineered in a precise way, and in bulky stock. The socket weld ball valve is a kind of weld ball valves.

Comparing to the butt weld ball valves, the socket weld ball valves are easier to install but the weld joint only can resist about 1/2 strength of butt weld ball valves.

In addition, due to the socket welding, a certain gap is needed to allow the pipe insertion and thermal expansion, but the existence of the gap will cause certain consequences.

Especially when your application is some corrosive fluid, the liquid will remain in the gap for a long time, and these discontinuous pipe internals are easy to be corroded.

The Socket Weld Ball Valve is manufactured in a state-of-the-art facility, following international standards of manufacturing.

We give you the flexibility to select a Socket Welded Ball Valve according to your need and choice.

The selection of the Ball Valve Socket Weld can be made by carefully reading the description of each type on our page.

The international standards of ASME and API are followed during the manufacturing and extensive testing is performed before coming to the stock.

Different sizes are available as per the need of the customer from 1/4” to 4”. The main feature of the Socket Welded Ball Valve is its capacity to prevent leakage and bearing high pressure.

These properties of being a leakage prevent and the high-pressure handling capability of the ball valve are due to the socket weld connections.

The blow-out-proof steam design of Socket Welded Ball Valve also makes it more applicable for steam-related applications.

The Seat for Socket Welded Ball Valve is made of PTFE as a standard high-performance machined seat.

Kinvalve gives you the flexibility to select padlocking, anti-static device, Pre-load Belleville washers for self-adjustable packing, V-ring packing, and O-ring stem seal, as options for your selected valve.

Efficient and Convenient Socket Welded Ball Valve

We offer Socket Welded Ball Valve with 3-piece construction, floating Ball, as well as Socket Welded Ball Valve with 3-way construction and Floating Ball.

The detailed description and the specifications are mentioned on our site for your ease and comfort. The name of Socket Welded Ball Valves come from the way that the pipe serts into their end connections through welding.

This socket welded type of end connection gives the edge of dropping the leakage level to the lowest limit. The socket Welded Ball Valve is used where prevention of leakage is very essential like for oil and gas-related applications.

Kinvalve offers the Socket Welded Ball Valve in different sizes ranges from ¼” to 4”, available in stainless steel, carbon steel and other special alloys are also upon request.

To accommodate you in terms of pricing, different options are available in Socket Welded Ball Valve to reduce the cost of Socket Welded Ball Valve by eliminating the unnecessary features. The details of available options are as below:

  • Blow-out Proof Stem

Blow-out-proof stem in the Socket Welded Ball Valve adds safety to the valve.

This method helps the valve to bear more pressure during the flow and helps the valve to sustain.

The stem is inserted from the inside of the valve with an integral T-Type shoulder to prevent it from blowing out.

This technique of inserting a stem from inside the valve prevents the stem from being pushed out by the pressure from the valve inside. It assures that the stem is sealed safely.

  • Anti-Static Feature

Static electricity is a very common phenomenon in valves. This static electricity is produced when there is a flow of fluid through the valve due to the transfer of electrons.

The friction between the ball and the non-metal seat ball, body, and stem produces static charges. This phenomenon of static electricity enhances the chances of a fire in the entire pipe system.

The Socket Welded Ball Valve contains an anti-static device to reduce the chances of static electricity. 

  • Padlocking

Padlocking is a mechanism to lock the Socket Welded Ball Valve in close condition for prolonged periods. This mechanism provides the edge to the workmen while he is working on the machinery.

  • ISO5211 Mounting Pad

ISO5211 Mounting Pad and Stem Sizes

If there is a requirement of automation for the Socket welded ball valve, the mounting pad can be very helpful. The ISO 5211 certified mounting pad is used to couple the actuator.

The built-in option of the mounting pad in the Socket welded Ball valve eliminates the play and gives improved actuator positioning capability. The mounting pads available with Socket Welded Ball Valve fit a wide range of actuators.

The option of a mounting pad on the Socket Welded Ball Valve gives the flexibility to use various types of actuators in the future even after installation.

  • Fire Safe Design

Fire-safe design in Socket Welded Ball Valve gives it the capability of bearing high temperature. These Socket Welded Ball Valves are designed in such a way that the material and the structure can pass the fire situation with limited leakage.

To prevent the internal leakage in Socket Welded Ball Valve, the ball is being pushed by the upstream pressure to the downstream metal seat. The following figure shows the procedure.

  • Multiple stem Seals Design

Multiple-Stem-Seal-Design-in-SW-Ball-Valve

Multiple Stem Seals in Socket Weld Ball Valve

A traditional stem seal design like V-ring or cup-and-cone stem packing is fair enough to combat the most fluid leakage.

But if you have to handle the most crucial conditions such as the applications of hazardous volatile chemicals with extreme fluctuations in temperature and pressure, you should consider more on the seal design things.

When the socket welded ball valves are equipped with an actuator, you should think about the side-load protection to combat the misalignment, improper manual or abusive contact.

In order to compensate the drastic fluctuations in temperature and pressure, you should select the live-load stem packing for your SW ball valves.

When comes to fight for the fugitive emissions, you also need to consider the seal materials and also the gaskets for the body joints which is suitable for your fluid flow characteristics and application requirements including fire-safe request, working temperature, volatility, gas or liquid.
