The safety solenoid valves for gas series VSC are manufactured in accordance with EN161 and are suitable for the automatic control of gases belonging to the first, second and third air family. They are normally closed solenoid valves for continuous and cyclic operation, by energising the coil the valve opens and in the absence of power the valve closes rapidly. They comply with EU regulation 2016/426 and SIL 2 and 3 (with 2 solenoid valves and leakage control).
