SVX (with Remote Stop) Hazardous Area Energized to Open Air Shut Off Valve

The Chalwyn SVX flameproof energize to latch open valve with manual open/stop lever is designed with “fail safe” actuation in hazardous area applications. The valve is opened using the manual start/stop lever. After the valve has been opened power is applied to the solenoid. The valve is held open as long as power is supplied. When power is cut off for any reason such as the detection of an engine overspeed condition or other unsafe engine operating conditions, the valve will close.
