Air pressure must be applied to these PVX valves to open to the engine run position and needs to be maintained between 4 and 8 bar to hold the intake valve fully open whilst the engine runs.

PVX-301, PVX-501 & PVX-801
With no air pressure applied to these PVX valves they will be fully open and the engine may run. To carry out an emergency stop, apply an air pressure of 4 to 8 bar to close the intake shut down valve. The supply pressure must be vented before attempting to re-start the engine.
