Product features

Explosion proof electric stop valve is applicable to flammable and explosive working conditions. It is mainly composed of explosion-proof electric actuator and stop valve, which is driven by power supply to open or close the valve. The protection grade of explosion-proof electric stop valve is IP68, and the performance of the actuator meets the provisions of JB/T8528-1997 technical conditions. It is suitable for steam and oil pipelines, and has the characteristics of high temperature resistance, strong operation function, high safety factor, stable performance, etc.

Working principle of explosion-proof electric stop valve:
 
Explosion proof electric stop valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve from below the valve disc, the resistance to be overcome by the operating force is the friction between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the shut-off valve is greater than the force to open the shut-off valve, so the diameter of the valve stem should be larger, otherwise the valve stem will be bent.
