Imported stainless steel explosion-proof liquid ammonia solenoid valve is mainly suitable for low-temperature media such as ammonia, ammonia gas, liquid ammonia, liquid carbon dioxide, and gas. Liquid ammonia explosion-proof solenoid valve The scope of work includes liquid nitrogen equipment, ammonia pipelines, gas pipelines, cooling equipment, metallurgical industry, petrochemical industry, electric power equipment, cryogenic equipment, experimental equipment, etc.;

The explosion-proof liquid ammonia solenoid valve mainly uses electric power as the driving current to generate electromagnetic force by driving the electromagnetic coil, and then the electromagnetic force controls the opening and closing of the solenoid valve by controlling the spring. During normal operation of the liquid ammonia explosion-proof solenoid valve, the spark arc generated by the electric energy is The components are placed in a flameproof enclosure. The flameproof enclosure can withstand the internal pressure without damaging the pipes suitable for ammonia, liquid ammonia, gas media or specially used for weakly corrosive media.

It is based on this principle that the pilot solenoid valve is more suitable for use under large diameter and high pressure conditions; Note that the circulating medium must have a certain pressure. Various pilot-operated solenoid valves produced by our factory require that the pressure of the medium should be greater than
