China Screw Connecting Pneumatic Ball Valve

Screw connecting pneumatic ball valve

1. Company profile
2. Products details
Pneumatic O type floating ball valve is special design based on absorb the advantage technology overboard, and crafted products. It controls and adjusts the pressure, flow, temperature, liquid level, etc., by connecting with electrical valve positioner, solenoid valve, limit switch, air fliter pressure reducting valve. Its power is compress air. Valve stem drive valve core turn 90 degree in valve, to achive the action of full close/open.
