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.

We offer custom configurations to fit your specific applications. Our valves are tested to strict OEM standards for shock, corrosion, vibration and life cycle.

The SVR series is also available in 44 mm (1 3/4”) and 64 mm (2 1/2”). Additionally, we offer custom configurations to fit your specific applications, plus a variety of different types of Chalwyn valves ranging in size from 25 mm (1”) to 229 mm (9”). Larger sizes are available within our other brands.
