What Are The different Components Of Wafer Ball Valves?

Wafer ball valves have quite a number of components that influence how the wafer ball valves work.

In other words, the wafer ball valves have different parts that work in conjunction with one another.

Here are some of the parts of the wafer ball valve that you should know more about.

Components of Wafer Ball Valve

Main Body

Theis the main frame or body of the wafer ball valve that houses and holds all the other parts of the valve.

Screwed Cover

Just from the name, you will note that the screwed cover is part of the wafer ball valve that covers the opening of the valve.

You can open it and close it very easily with screw aid by simply turning it either clockwise or anticlockwise.

Seat

This is a rubber piece of the wafer ball valves where the ball rests during the turning of the valve to open and close.

It creates a very tight seal when the ball rests on it thus preventing any form of leakage through the system.

Ball

This is the main part of the wafer ball valve with a hole through it that controls flow of fluids.

Depending on how you turn it, you can either open or close the passage of the fluids through the pipes.

Thrust Washer

These are special types of bearings that you can insert between rotating components and stationary components.

In this case, you will have the thrust washer between the ball and the seat thus keeping the ball in place.

Gasket

The gasket is a type of mechanical seal which will fill the space between two mating surfaces to prevent leaks.

Wafer ball valves have gaskets between different mating parts that help in the prevention of leakages.

Packing

The packing is a gland on the bonnet that pushes down on top of the V leading to expansion of packing.

As the packing expands, it will create a seal against the bonnet of the stem on the wafer ball valves.

Stem

The stem is the point of connection between the ball and the external control mechanism.

You can either have it connected to the lever or handle in a manual wafer ball valve.

Gland Flange

This is the part of the wafer ball valve that will compress or retain the stem packing within the stuffing box.

It will help in retaining or holding down the gland within the stuffing box of the wafer ball valves.

Lever

The lever is the external part of the wafer ball valve that you will use to turn the ball in different directions.

You can easily open and close the wafer ball valve by controlling the ball movement using the lever.

How Does Wafer Ball Valve Work?

Wafer ball valves use the principle of turning the hollow ball through different angles in order to control fluid flow.

The ball is usually sandwiched between two seats thus controlling flow of fluids through the pipeline.

Here is a demonstration of how the wafer ball valve works.

Most of the wafer ball valves have four holes that align within the connected pipeline.

It also has a valve that is designed in such a way that it clamps between two flanges within the pipe work.

Once you turn the lever on the external part of the wafer ball valve, it will also turn the stem.

As that happens, the stem will produce a significant turn on the ball at different angles.

At some point, the ball will turn at an angle that will align the hole with that of the pipeline.

In this case, the pipe will be open and the fluid will flow through the valve to other parts of the system.

You can also close the valve by turning it towards a different direction which will change the alignment of the hole.

This change will force the hole within the ball to face the walls of the pipe thus closing the system.

The fluids will not be able to flow through the valve and the rubber seal will also create very strong barriers.

In other words, it will create a barrier strong enough to prevent the fluids from leaking through small spaces.
