Pneumatic emergency cut-off valve is common sense

o pneumatic emergency cut-off valve with compressed air or nitrogen to remote control quickly, easy to use security, equipped with a remote signal feedback device, can be in remote control room directly aware of pneumatic valve operation state, enable just press the control button to other items in the specified time.

to cut off the pneumatic valve operation method:

o pneumatic emergency cut-off valve when the controller according to beforehand programmed procedure of a certain air reversing pneumatic valve output a signal, the reversing pneumatic valve action, bringing pressure instrument air through the reversing of the pneumatic valve switch into the pneumatic actuator cylinder cavity or inferior vena, drive piston movement to cut off the pneumatic valve fast or closed.

quickly cut off the pneumatic valve parameters:

air interface: RC /

power supply interface: M x.

and cylinder pressure: operation. - 。 Mpa

, emergency cut-off time: seconds or less

: nominal diameter DN -

, the structure length: GB -

and connecting flange: JB/T -

working temperature: - ℃ ~ +

, nominal pressure:. - 。 Mpa

and applicable medium: ammonia, gas

and voltage: DCAC

emergency cut-off pneumatic valve main material:

the whole material: WCB

sealing surface: STL ptfe

packing: flexible graphite ptfe

o pneumatic emergency cut-off valve installed in the factory production workshop pipeline, explosion-proof solenoid pneumatic valve ( Pneumatic components) The power supply and distribution control system ( DCS） , programmable controller ( PLC） Or switch signals, such as leak detection instrument, pressure control instrument connections. Found in leak detectors, pressure control instrument ( Pressure is too high/low) Electricity ventilation closed, to avoid the situation for the first time to cut off the gas source, affect the normal production. To ensure the safety of the staff.
