Mechanical Gas Shutoff Valves <br /> A gas shutoff valve is required for all systems protecting + <br /> gas fueled appliances. A mechanical means of stopping <br /> gas flow is provided by'the Models BFGV-75/100/125 <br /> ! 150 / 200 / 250 ! 300 Gas Shutoff Valves. It is <br /> j connected to the Systems Releasing Module with: <br /> � • 1/16" (0.16 cm) stainless steel cable enclosed in 1/2" <br /> (1.3 cm) EMT conduit with a corner pulley at each <br /> change of direction. <br /> • Buckeye Shielded Cable which does not require a <br /> corner pulley at each change of direction or conduit. <br /> • A combination of both. <br /> The valves are rated for natural or LP gas(see Figure 2- <br /> 10)and are available in the following sizes: <br /> Figure 2-8. <br /> Model MB-2, Valve Maximum <br /> Shown With BFR-20 Cylinder Model Size Operating <br /> Number In(cm) Pressure <br /> Remote Mechanical Pull Station BFGV-75 '/(1.9) 5 psi (4 bar) <br /> BFGV-100 1 2.5) 5 si .4 bar <br /> BFGV-125 1 '/(3.2) 5 psi (4 bar) <br /> Thei Model RPS-M Remote Mechanical Pull Station gFGV-150 1 %z 3.8) 5 psi 4 bar) <br /> provides remote mechanical actuation of the Systems , gFGV-200 2 5.1 5 psi(4 bar) <br /> Releasing Module.
