Gas solenoid valves

Solenoid valves are installed in hydraulic systems and have the function of closing or opening a passage of a fluid through an electrical contact. Unlike normal taps, solenoid valves do not open manually but work thanks to the impulse that is sent by a solenoid that moves the internal mechanism of the solenoid valve, thus triggering the opening or closing of the valve. 

Solenoid valves allow the passage of a fluid (liquid or gaseous) through the gap identified by the valve itself. A solenoid valve is composed of a solenoid (electromagnet) and the valve body. For the gas industry, these products are specifically made for methane gas, to be installed even in contexts at risk of explosion. (Atex)
