Overview

The Chalwyn MPX Pressure to Close Butterfly Valve with Manual Close is designed to mechanically latch in the open position for the diesel engine to run. In the event of an engine overspeed condition, direct pneumatic pressure is applied to release the latching mechanism and allow positive spring action to close the valve. The valve is designed to be opened manually. The valve includes options for a microswitch position indication, local stop button close, pushbutton manual cable close, and pull “T” handle manual cable close.
