EVRMNC EVRM6NC Safety solenoid valves for gas with manual reset, normally closed The EVRM-NC type valve is a manual reset safety valve that is normally closed. When the coil is not energized the spring works on the shutter keeping the gas passage closed. Simply by energizing the coil the valve does not open. It is necessary to manually […]
EVRMNA EVRM6NA The EVRM-NA type valve is a manual reset safety valve that is normally open. A manual operation is therefore necessary to open the valve and set the mechanism consenting to maintain this state. The powering by means of line current and/or condenser discharge, induced by the leakage detector, causes tripping of the mechanism and consequent closing of the gas passage. If energizing of the sensor persists due to the presence of gas, the valve remains under power and does not allow reset.
