Gas safety solenoid valve (normally closed)

Nominal pressure:PN1.6MPa
Nominal diameter:DN15~400mm

ZCRP50-400dSB normally closed gas safety solenoid valve is a safety device in gas transmission and distribution system. It is installed on the high pressure side of the gas regulator box and the regulator station, on the medium pressure pipeline of the underground pipe gallery of the urban gas transmission and distribution system, on the main introduction pipeline of the gas medium pressure direct into the household gas system of the boiler room and civil and facilities, and connected with the gas alarm. When there is a gas leak or an unexpected power failure, the valve is quickly closed to cut off the gas source, prevent the occurrence of gas explosion accidents, and ensure the safety of users.


In normal operation, the internal circuit of the solenoid valve is converted into a very low holding voltage after opening the valve, which reduces the coil temperature opening of the solenoid valve and saves electric energy.


When the gas leak alarm, only one instantaneous power signal, or power failure can quickly close the solenoid valve, safe and reliable. Excellent sealing performance, zero leakage.
