Note: 1. Pneumatic diaphragm valve can still be attached with feedback signal, limiter or positioner to meet the needs of self-proximity control, program control or flow regulation.
2. The feedback signal of the pneumatic valve adopts non-contact sensing technology.
3. The cylinder piston type is adopted.
4. When the air source fails, the valve can be opened by operating the handwheel.
