Use comparison of electric and solenoid valves

Solenoid valve: for liquid and gas pipeline switch control, is two DO control. Generally used for small pipe control.
Electric valve: for liquid, gas and wind system pipe medium flow analog regulation, is AI control. In the control of large valve and wind system can also use electric valve to do two switch control.
Solenoid valve: can only be used as switching quantity, is DO control, can only be used for small pipe control, common in DN50 and below pipe.
Electric valve: can have AI feedback signal, can be controlled by DO or AO, more commonly seen in large pipelines and wind valves.

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
