XT Butterfly Valve

Chalwyn XT Butterfly Valve


The Chalwyn XT range uses the best available technology to shut down a runaway diesel by positively choking off engine intake air. The valve operates as part of a fully automatic overspeed shutdown system when paired with our Revguard 2 speed switch and activation kit.

Actuation of the XT solenoid rapidly closes the valve’s butterfly disc which shuts off intake air flow into the engine.
