Solenoid valves are PED certified (CE 0496 and CE 0497) and are designed to be installed on the gas supply pipe and connected to a gas leak detection system.
These valves shut off the gas flow when a detector or control device in the protected area sends a hazard signal.
All solenoid valves feature manual reset in accordance with CEI UNI EN 50194 for gas detection systems.
Made of brass and available in sizes from ½ inch to 2 inches, these valves offer simple, reliable and safe operation.
To prevent unwanted closure caused by brief interruptions in the power supply, the normally closed (N.C.) 230 V~ manual reset solenoid valves are equipped with a power supply system that disregards short power interruptions (< 30 ms).
The N.C. solenoid valve requires a continuous power supply while open and closes only on a command from the detector or in the event of a power failure.
Because this mechanism ensures closure even during a power failure (positive safety feature), it provides a higher level of safety than normally open (N.O.) solenoid valves.
The solenoid valve is normally positioned after a filter, outside the protected area, and upstream of the regulation components.
The valve must be installed with the arrow on its body pointing in the direction of gas flow.
Reset is performed manually. After unscrewing the threaded lower part of the valve, use the button to push the piston upwards along its axis. After resetting, screw the relevant part back into place.
