Frequently Ask Questions

What Is a Pneumatic 2-Piece Flanged Ball Valve?

It is a two-piece ball valve with flanged ends and a pneumatic rotary actuator for automatic opening and closing. It is widely used for industrial valve automation.

How Does a Pneumatic Ball Valve Work?

Compressed air operates the pneumatic rotary actuator, which rotates the ball approximately 90° to open or close the valve.

Who Is a Pneumatic 2-Piece Flanged Ball Valve Manufacturer in India?

Alis Valves manufactures and supplies Pneumatic 2-Piece Flanged Ball Valves for automated industrial isolation and flow control applications.

What Accessories Are Used?

Common accessories include solenoid valves, limit switches, AFR/FRL units, positioners, and manual override systems.

What Are Pneumatic 2-Piece Flanged Ball Valves Used For?

They are used for automated isolation and flow control of water, oil, gas, air, steam, chemicals, and other compatible fluids.

How To Choose a Pneumatic 2-Piece Flanged Ball Valve?

Consider valve size, pressure rating, media, temperature, body and seat materials, flange standard, actuator torque, air pressure, and fail-safe requirement.

What Is Fail-Safe Operation?

Fail-safe operation moves the valve to a predetermined position when the air supply fails. Common configurations are Fail Open (FO) and Fail Close (FC).
