Technical features

Normally open type

ZCRP15-400dSK gas safety solenoid valve is suitable for safety devices in gas equipment pipeline transmission and distribution systems. It is usually installed on the main pipeline of the gas system and connected to the gas alarm. When the gas alarm detects a gas leak, it sends an action signal to the solenoid valve to quickly cut off the gas source to prevent the leaked gas concentration from reaching the explosion limit and prevent gas explosion accidents.

Normally closed type

ZCRP50-400dSB normally closed gas safety solenoid valve is a safety device in the gas transmission and distribution system. Installed on the high and medium pressure side of the gas pressure regulating box and pressure regulating station, on the medium pressure pipeline of the underground pipeline corridor of the urban gas transmission and distribution system, and on the main inlet pipeline of the gas system of medium pressure direct entry into the household such as boiler rooms and civil facilities, it is connected to the gas alarm. When a gas leak occurs or an unexpected power outage occurs, the valve quickly closes and cuts off the gas source to prevent gas explosion accidents and ensure the safety of users.

During normal operation, the internal circuit of the solenoid valve is converted into an extremely low holding voltage after the valve is opened, which reduces the temperature of the solenoid valve coil and saves electricity.

When the gas leak alarm is triggered, only an instantaneous power signal is needed, or the solenoid valve can be quickly closed when the power is off, which is safe and reliable. Excellent sealing performance, zero leakage.
