What is a Flanged Ball Valve?
Flanged 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 ball 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.
What is Flange?
Stainless flange dimensions may differ for flanged ball valves. The most important feature of the valves produced with stainless flange is their high durability. Stainless flanges have different types and different flange sizes depending on where they are used. Stainless blind flanges and normed flanges are produced in different sizes and are used in stainless ball valves. 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.
Scope of Application
- Air, gas and liquid applications
- Drains and vents in liquid, gas and other liquid services
- steam service
- food facilities
- chemical industry
- Paper-pet vs. recycling areas
Advantages and Disadvantages of Ball Valves
- Fast on-off operation
- Low torque tight sealing
- Smaller in size than most other valves
- 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.
