  •  Explosion proof electric stop valve

Product overview

The explosion-proof electric stop valve is suitable for 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 the explosion-proof electric stop valve is IP68. The performance of the actuator conforms to the technical requirements of JB / t8528-1997. It is suitable for steam and oil pipelines. It has the characteristics of high temperature resistance, strong operation function, high safety factor and stable performance.

Working principle of explosion-proof electric stop valve:
 
The explosion-proof electric stop valve belongs to the forced sealing type 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 the lower part of 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 cut-off valve is greater than the force to open the cut-off valve, so the diameter of the valve stem should be larger, otherwise the valve stem will be bent.
