SVR-3XX Compact Butterfly Valves

SVR-3XX Compact Butterfly Valve


The Chalwyn SVR range is a compact butterfly design air intake shutoff valve available with electrical or mechanical actuation. Actuation of the SVR solenoid rapidly closes the valve’s sealing element which shuts off intake air flow into the engine.

The SVR can be used in fully automatic or manual shutdown systems. When incorporating into an automatic overspeed shutdown system, this valve is compatible with Chalwyn CSX-300 range and Revguard speed switches.
