Q: closely block valve pneumatic answer: common sense often closely block valves open type pneumatic see fit to use compressed air or nitrogen gas and then quickly stem over a long distance, use convenient, security with long-range signal feedback device, can be in long-distance stem chamber directly obtained above, the operation of the start using only according to curb the keys left things at project completion within the time specified. Block valve operating way: o pneumatic closely block valves when the stem, make good formalities in advance of a certain air reversing valve output a signal, the directional control valve action, bringing pressure instrument air after reversing valve switch into the pneumatic actuator cylinder cavity or inferior vena, drive piston movement makes the block valves fast on or off. Marine valve block valves technology rapidly depending on a parameter: 1, air interface: RC1/42, power supply interface: M20 x 1. 53, cylinder operating pressure: 0. 3 - 0. 6 mpa4, close off time: 3 seconds or less 5, nominal diameter: DN25 - Length: 4006, structure GB12221 - 897, petition flange: JB/T81 - 948, office temperature: - 40 ~ + 420 ℃ 9, nominal pressure: 1. 6 - 4. 0 mpa10, suit to use media: ammonia, gas 11, voltage: DC24AC220 closely block valves main material: material: group 304 WCB tightly closed surface: STL ptfe packing: flexible its ptfe often open air tight block valves installed in the factory production line, explosion-proof solenoid valve, Pneumatic components) The power supply and distribution stem system ( DCS) , programmable stem ( PLC) Or leak out observation instrument, switch signals, such as pressure to curb the spectrograph signatures. In agent volume viewer find leakage, pressure stem spectrograph ( Pressure is too high/low) Electricity ventilation close to 1 time cut throat gas source to prevent the situation occurs, affect the normal produce. 。 To ensure the safety of office positions. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
