- Note:
- Pneumatic diaphragm valve also can be installed feedback signal, limited mchine, air combination or solenoid Valves in order to adapt to the requirements of automatic control, programed control or flow rate adjustment.
- The feedback signal of pneumatic valve is adopted the sense technology of non-contact.
- Adopt film cylinder in place of piston cylibder, which remove the aduse that piston ring is easily damaged and lead to not open or close valve.
- When are soutce happen to trouble can operate handwheel to open the valve.
