The operating principle of the normally open EV131/136 solenoid valves is very simple and therefore extremely safe. The electromagnetic coil, if subjected to voltage, releases the closing device of the valve which is normally open. The reset is manual to check the causes of the gas interception. During normal operation there is no electrical absorption and therefore, in addition to saving energy, no member is subjected to wear.
Normally open gas shut-off valves with manual reset, they are suitable for gas shut-off for danger signals sent by gas presence detectors (methane, LPG, carbon monoxide and others), safety thermostats, etc.
They can only be reset manually and only when they are not electrically powered.
They are equipped with VPI (Visual Position Indicator) for visual signaling of the position of the valve actuator. When the valve is closed, the red band normally hidden by the reset knob is visible.
The RMOC NA versions are also equipped with a button for manual closing of the solenoid valve which can be used as a substitute for a manually closing tap.
