Benefits Of Pneumatic Gate Valves:
COVNA pneumatic gate valves are available in soft seal types and hard seal types to meet various industrial needs. Equipped with piston pneumatic actuator which has a higher torque range to ensure the gate valve could be open/close easier and fully. There will be 2 limit switches on it. One displays the situation of open and the other is display the situation of close.
