Typical applications • Fuel shutdown or idle valve on diesel or gasoline engines • Senses pressure drop from a hydraulic system circuit • Suitable for mining machinery and ideal for other machinery where monitoring is done without electricity Key benefits • Positive fuel shutoff (without needle valve) • Engine to idle (with needle valve) • Mounts easily • Low friction seals • Excellent repeatability • Operates on engine oil pressure

Hydromechanical Diesel Fuel Shutoff Valve - Model 4164 Operation Typical use in Low Oil Pressure / High Water Temperature Shutdown system. Orifice 2185 required to provide fast vent on High Water Temperature fault. Notes 1. Rise of trip setting per 100 psi (6.9 bar) rise of fuel pressure = 2 psi (0.14 bar) 2. Max. working pressure: Fuel IN port = 200 psi (20.7 bar) Pressure P port = 150 psi (10.34 bar) 3. Reset knob must return to run position after machine starts To start, the valve reset knob must be set at the ‘start’ position. After the engine starts the reset knob will automatically go to...
