ZXT Pneumatic Diaphragm Valve is composed of pneumatic diaphragm actuator and diaphragm valve. Because the valve has smooth flow channel, the restricting element is elastic diaphragm and there is no packing box on the bonnet, circulation ability is better than common control valve without leakage. The flow character of this valve is quickly open, the way to improve adjustable character is usage of locator. Within suitable differential pressure it could be used as shut off valve.
The positive and negative actuator can make pneumatic on and pneumatic off happen. This valve is suitable for adjustment of high viscous liquid, suspended particle, textile fiber, poisonous medium and corrosive medium.
