Solenoid Valve

NORMALLY-OPEN MANUAL RESET SOLENOID VALVES TYPE M16/RMO N.A. EEX - M16/RMOC N.A. EEX - M16/RM N.A. EEX

DESCRIPTION
The fonctioning principle of M16/RM N.A. EEX is very simple and extremely safe. The coil, when under tension, releases and springs up the closing device. The reset is manual to check the causes for gas detection. During normal conditons there is no electric absorption, no wear and tear.The versions M16/RMOC N.A. EEX can be equipped with a button that allows to close manually the gas substituting the manual tap of the gas line allowing also to test at intervals the good working of the solenoid valve.

EVP/NC - EVPC/NC AUTOMATIC NORMALLY CLOSED SOLENOID VALVES

DESCRIPTION
Gas interception automatic normally closed solenoid valves that open when the coil is powered and close when there is no tension. These solenoid valves can be controlled by pressure switch, thermostat, etc.
They can be equipped with a flow regulator (models EVPF/NC - EVPCF/NC). The solenoid valve can be supplied also with the closed position indicator switch (CPI Switch). Reference standard EN 161

In conformity with:
2009/142/EC Gas Directive

NORMALLY-CLOSED MANUAL RESET SOLENOID VALVES TYPE M16/RMO N.C. - M16/RM N.C.

DESCRIPTION
This solenoid valve is made to guarantee the gas interception either for gas detector signals (methane, lpg, carbon monoxide and so on) and safety thermostats, or for an electric black out. In order to be more reliable this solenoid valve can be reset only when electrically supplied and only if the gas detector doesn’t send any danger signal.
Simply powering the coil does not open the valve. The reset mechanism has to be operated by hand.
