Catering Parts UK PROPANE GAS HILO/HI LOW CYLINDER GAUGE LPG.PRESSURE | PROPANE BOTTLE GAS LEVEL DIAL INDICATOR AND LEAK TESTER SAFETY FITTING

Note about the use and operation of this gauge: This valve contains a built in excess flow safety valve, this is designed to stop the gas flow in case of a cut or large leak in the pipe further down the gas line. This prevents gas flowing through when not connected to an appliance, i.e if you were to connect this to your gas bottle, then open the bottle, gas would NOT flow through as nothing is attached further down the line. Once connected to the regulator and the gas appliance the display dial must then be pressed inwards to allow gas to flow as it has a push/pull button function that controls the flow valve.
