EVRM-NA valve is a solenoid safety valve available as Normally open. It has to be reset manually. This means that the valve mechanism has to be manually manipulated to open the valve and keep it open. This feature is provided for a special purpose.
In the eventuality of gas leak, the leakage detector connected to the valve signals the presence of gas and causes the valve mechanism to trip. The gas passage shuts down and the operation is locked. If the sensor indicates continual gas presence, the valve mechanism does not allow resetting the valve to open.
When the underlying factors of gas leaks are removed, the valve has to be manually reopened and gas passage resumes. Thus it provides a high rate of safety. The valve can accommodate multiple leakage detectors and/or alarm systems to give accuracy in the detection of harmful gases like carbon monoxide. The valve locks operations on the gas-line and prevents accidents.
The valve is powered by a line current or condenser discharge. Its materials/connections are CuZn Rp3/8 GI AlSi Rp3/8 Rp2-1/2 DN40 DN 300.
