ASCO explosion-proof solenoid pneumatic valve can achieve highest explosion-proof pressure

how much ASCO explosion-proof solenoid pneumatic valve can achieve highest explosion-proof pressure, ASCO explosion-proof solenoid pneumatic valve
ASCO explosion-proof solenoid pneumatic valve principle: electricity, electromagnetic force open the pilot hole, the chamber pressure drops rapidly, in closed form around the high low differential pressure, fluid pressure push close up, pneumatic valve open; Power off, the spring force to close the guide hole, inlet pressure chamber through the bypass hole quickly shut in pneumatic valve using a form around on high pressure difference, fluid pressure push close move down, close the pneumatic valve.
working pressure difference, line the high pressure difference is less than. MPA should choose ningbo al parker company such as ZS, W, ZQDF, ZCM series and type of moving step by step straight acting; Differential pressure is greater than the minimum work. The MPA guiding type (optional Differential pressure type) Solenoid pneumatic valve; Maximum working pressure difference should be less than the biggest calibration pressure solenoid pneumatic valve; General electromagnetic pneumatic valve is unidirectional, so should pay attention to whether there is a pressure difference, if you have installed check pneumatic valve.
fluid cleanliness is not high when the filters should be installed in front of the solenoid pneumatic valve, general cleanliness requirements for medium pneumatic valve is better.
note flow pore size and diameter. Two solenoid pneumatic valve usually only switch control; Conditions permit, please install bypass pipe, easy maintenance; When there is water hammer to customize solenoid pneumatic valve opening and closing time to adjust.
pay attention to the environmental temperature on the influence of pneumatic valve
power supply current and power consumption should be selected according to the output capacity, power supply voltage generally + % to the left or right, must pay attention to communication when starting the VA value is higher.

reliability solenoid pneumatic valve normally open and normally closed; General selection normally closed type, electric open, power is shut down; But when opened for a long time closed in very short time to choose the normally open type.
life test, the factory generally belongs to the type testing project, specifically our country haven't professional standards of electromagnetic pneumatic valve, so careful when choosing solenoid pneumatic valve manufacturer.
action time is very short at high frequency generally choose straight acting, large-caliber choose fast series. ASCO explosion-proof solenoid pneumatic valve can achieve highest explosion-proof pressure,
ASCO explosion-proof solenoid pneumatic valve is short work repeatedly and short work of three. Explosion-proof solenoid pneumatic valve are long-term duty, namely the coil allows electricity to work for a long time. Pneumatic valve opened for long for only a short time off, appropriate chooses normally open solenoid pneumatic valve. In short work and batch is large, can make special order to reduce power consumption.
ASCO explosion-proof solenoid pneumatic valve working frequency: the frequency requirement is high, the structure should be optimized direct acting solenoid pneumatic valve, power supply to optimizing communication. Role of
explosion-proof solenoid pneumatic valve of the coil housing not only has the stress of gas explosion and isolation effect, but also for gas explosion energy transfer have block effect, higher safety performance. Is the special design is applicable to transport inflammable and explosive media or dedicated to explosive dangerous sites of special electromagnetic pneumatic valve series products, different environment and fluid should choose different level of explosion-proof solenoid pneumatic valve.
ASCO explosion-proof solenoid pneumatic valve has closed cavity, in a different location to open a hole, each hole leads to different tubing, cavity pneumatic valve is among, both sides are two electromagnets, which face the magnet coil electricity pneumatic valve will be attracted to which side, by controlling the movement of the pneumatic valve body to blocked or leakage of different discharge of oil hole, and the oil hole is always open, hydraulic fluid will enter the different oil drain, and then through the oil pressure to push oil just the pistons, piston drives the piston rod, piston rod drive mechanism. So that by controlling the electric current of the electromagnet to control the mechanical movement.
