Note: 1, the pneumatic diaphragm valve can still be attached to the feedback signal, limiter or positioner to adapt to the needs of near-control, program-controlled or regulating flow.
2, pneumatic valve feedback signal using non-contact sensing technology.
3, the use of piston-cylinder.
4, when the gas source fails, the handwheel can be operated to open the valve.
