Key features

Intrinsically Safe Pneumatic Drive: No electric spark risk, natural explosion-proof performance, priority for flammable chemical, oil and gas hazardous zones.

Two Fail-Safe Action Modes: Air-to-open / air-to-close configurable to ensure valve fails at safe opening when instrument air cuts off, prevent runaway temperature/pressure accidents.

Manual Handwheel Backup: Realize on-site manual adjustment when air supply or positioner fails, avoid whole production line shutdown.

Product Q&A

Q:Single-seat vs double-seat pneumatic diaphragm valve

Single-seat: Tight sealing, big unbalanced force, suitable for small flow, high pressure difference; Double-seat: Balanced plug, small thrust demand, large flow coefficient, slightly higher leakage, for large flow medium pressure difference pipelines.

Q:Standard signal and air supply

Standard control signal 4-20mA DC; instrument air supply pressure 0.04-0.06MPa; air source needs drying and filtration purification.

Q:Can it achieve full tight shut-off?

Single seat soft seal realizes near bubble-tight shut-off; sleeve type has slight residual leakage, not for strict zero leakage isolation.
