BGTWA Modulating Wafer Rubber Seal Pneumatic Butterfly Valve
Pneumatic Butterfly Valve Technical Parameters:
1.Pneumatic butterfly valve can be equipped with pneumatic actuator which controlled by solenoid valve, can be used as a cut-off pneumatic butterfly valve, with pneumatic actuators which has positioner can be used
as a regulated type pneumatic butterfly valve.
2.According to user requirements, the pneumatic butterfly valve with pneumatic actuator can be equipped with positioners, air filter reduce pressure regulator, limit switch, hand wheel, solenoid valve.
3.BGTWA Series middle-line wafer type pneumatic butterfly valve,using BGT series pneumatic actuator
4.BAWWA Series pneumatic wafer middle-line butterfly valve,using BAW series pneumatic actuator.
5.The pneumatic control butterfly valve has small size, light weight, reasonable structure, easy installation,
and is suitable for high-volume low-pressure fluid control and regulation of solid powder, closure and so on.
