What is a 2 Pieces Stainless Steel Ball Valve?

2 Piece Stainless Ball Valve; It is a quarter-turn rotary valve that uses a spherical shaped disc to stop or start flow. It is defined as a mechanical device that directs and modulates the flow of various types of liquids through the opening of a sphere with an opening in the middle of the valve. By turning the handle on the valve, it manually opens/closes the port that controls the pressure from the flow of fluid. Durability and excellent shut-off are features that make the ball valve advantageous over other valve types.

How Does 2 Pieces Ball Valve Work?

More complex control systems that use valves that need to regulate flow through a pipe will need an actuator. The actuator controls the valve pneumatically or electrically and ensures that the fluid’s flow is properly positioned to be sensitive to varying pressures and flow levels. Features to consider to determine the appropriate valve will be temperature and pressure, number of ports, valve size, body material type, end connections and configurations.

Advantages and Disadvantages of Ball Valves

Advantages

Fast on-off operation.
Low torque tight sealing.
Smaller in size than most other valves.

Disadvantages

Conventional Ball valves have poor throttling properties.
In slurry or other applications, suspended particles can settle, become trapped in body cavities and cause wear, leaks, or valve failure.
