The EVRM-NC solenoid valve is a normally closed safety valve that can be manually reset. In the inactive state, the spring acts on the valve core to prevent the passage of gas. Power the coil, but the valve does not open. The reset rod on top of the valve must be manually moved to open it.

In this case, the valve can remain open. The valve quickly closes in the absence of current and remains closed even after the current returns. After solving the problem, the valve opening needs to be manually performed according to the above method. This type of device can be connected to one or more pressure switches, suitable for locking operations in the absence of gas, air, or current, and suitable for continuous operating conditions (always under voltage).
