CHALWYN


The HVX series air intake shut down valves are designed to be latched open by engine oil pressure. Manual start override is via a cable from a remote lever assembly. Once the engine is running, the valve is held in the run position by lubricating oil pressure. Valve closure will occur if the oil pressure drops below about 20 psi. Emergency manual stop is by returning the lever to the stop position.
Models are suitable for both hazardous and non-hazardous area applications, and are available in basic flange mounted form or fitted with hose adaptors and/or flametrap housing.

Oil (or air) pressure latched open shut down valves, with manual start override and manual emergency shut down. Slim, light weight, 3" and 5" bore butterfly valves with cable and lever start override to enable the valve to be held open prior to supply of oil (or air) pressure. Shut down occurs on loss of oil (or air) pressure or by operation of the manual shut down control. These valves may be mounted between flanges or can be supplied fitted with hose adaptors selected from a range of 26 size options.
