The operation of bistable solenoid valve

Bistable solenoid valves power supply pulsating 120V direct current, can be positive or negative. When the pulsating dc voltage of different polarity is applied to the solenoid coil, the spool will move in different directions. When power is stopped, the spool will stop at the end of the movement. There is only body and coil inside the bistable solenoid valve, so the volume is smaller than that of unistable solenoid valve. In addition, when the spool is in any state, no power is required, so the power consumption is very small.

A brief introduction of explosion proof coil

1. Introduction of foreign advanced technology, use flame retardant casting materials to encapsulate the electrical components in the enclosure 2. Internal fuse tube, pressure sensitive resistance and other elements can enhance the explosion proof performance and work stably and reliably 3. The cover adopts zinc alloy material to withstand the impact force of more than 20J 4. The  explosion proof coil  has a wide application surface, and the static iron core seat and high-energy energy can be matched with the coil to assemble the explosion-proof electromagnetic valve Explosion proof coil  can be equipped with two - way, two - way, two - way, two - five - way, three - five - way and other series of explosion-proof electromagnetic valves.

Explosion proof coil

Explosion proof coil  is widely used in explosion-proof places in coal mine, petrochemical industry, smelting, liquefied gas and natural gas industries. Details of  ex-proof coils 1. Introduction of foreign advanced technology, use flame retardant casting materials to encapsulate the electrical components in the enclosure 2. Internal fuse tube, pressure sensitive resistance and other elements can enhance the explosion-proof performance and work stably and reliably 3. The cover adopts zinc alloy material to withstand the impact force of more than 20J 4. Wide application surface, the anti-explosion electromagnetic valve can be assembled by matching static iron core and high-energy energy with the coil The  explosion proof coil  can be equipped with a series of explosion-proof solenoid valves, including two two-way, two three-way, two four-way, two five-way and three five-way, which are widely used in explosion-proof places in coal mine, petrochemical industry, smelting, liqu
