Low Pressure Cut-off Valve with UPSO 1 1/2" x 1 1/2" BSP
Safety valve which cuts off the gas following a loss of inlet pressure. The valve may be manually reset. The valve should be reset after inlet pressure has been restored and any taps and/or valves have been checked closed. It is in theory possible to re-pressurise the system if there is an escape path smaller than the 1 mm bypass valve. The valve shuts at the preset value of 15 mbar (6" wg). The valve must be mounted upright in horizontal pipework.
Cut-off pressure: 15 mbar (6" wg).
Threads: BSP female to ISO 7-1 (Formerly BS 21).
