Frequently Ask Questions
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.
Compressed air operates the pneumatic rotary actuator, which rotates the ball approximately 90° to open or close the valve.
Alis Valves manufactures and supplies Pneumatic 2-Piece Flanged Ball Valves for automated industrial isolation and flow control applications.
Common accessories include solenoid valves, limit switches, AFR/FRL units, positioners, and manual override systems.
They are used for automated isolation and flow control of water, oil, gas, air, steam, chemicals, and other compatible fluids.
Consider valve size, pressure rating, media, temperature, body and seat materials, flange standard, actuator torque, air pressure, and fail-safe requirement.
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).
