Explosion-proof solenoid valve

Explosion-proof Solenoid Valve Models: Ex / ZCSB / ZCSB14.5N / ZCSB16N / ZCF An explosion-proof solenoid valve is an automation actuating component specifically designed for hazardous environments where flammable gases, vapors, or dust are present. Its core function is the same as that of an ordinary solenoid valve, i.e., using an electromagnetic coil to drive the valve core to control the on/off or direction of fluid flow. The core difference lies in its explosion-proof structure and enclosure. The enclosure of an explosion-proof solenoid valve typically complies with international or national standards (such as IECEx, ATEX, CNEx) for flameproof (Ex d), encapsulation (Ex m), or intrinsic safety (Ex i). In terms of working principle, it uses the strength of the enclosure to withstand an internal explosion without damage and prevents flame propagation to the outside; or it limits the electrical energy in the circuit to prevent sparks, arcs, or hazardous temperatures. The main features of the explosion-proof solenoid valves produced by Kaivex Valve Group include high ingress protection (typically IP65/IP67), corrosion resistance, and high reliability. They are widely used in fluid pipeline automation control systems in industries such as petroleum, chemical, natural gas, pharmaceuticals, and coal mining, serving as key equipment for remote control and interlock safety.
