note: 1.The pneumatic diaphragm valve can still be enclosed and put feedback signal , limit location device or positioner, in order to meet the automatic control , need programme-controlled or of regulating the flow.
2. The feedback signal of the pneumatic valve adopts contactless sensing technology.
3. Adopting the membrane type air cylinder to substitute the piston type air cylinder, it is apt to decrease leaking but causes the drawback that can't open and close the valve to get rid of the piston.
4. When breaking down in source of the gas , can operate handwheels to make the valve open.
