914 GasGas Train, Shut-Off Valve and Pressure RegulatorShut-Off ValveNatural Gas Inlet The shut off valve represents the first stage in the gas train. In addition to the ignition system, this device becomes the safety to shut down theengine by simply cutting off the fuel supply. The gas inlet port is ¾” for the G914L04 or 1” for the G914L06 and TCG914L06models.Pressure Regulator The “Zero” Pressure Regulator receives a gas pressure from 12” to 14” H2O andreduces the gas pressure level to 0” H2O. Outlet pressure to the fuel stepper motor is preset and sealed to 0” H2O(-0.25” to 0.25”) during the engine production and engine testing process. Inlet and outlet ports are 1.0” NPT thread.Stepper MotorDEUTZ Corp. Guido Pesch DEUTZ AG.
