Product catalog summary
Overview: The document describes a four-way solenoid slide valve, known as the Run-Stop Valve G4G4, designed for rapid engine ignition and shutdown. It operates in two modes: Energized To Run (E.T.R.) and Energized To Stop (E.T.S.).
Specifications:
  • Electrical Characteristics: 12 VDC at 14 W and 24 VDC at 14.5 W, both for continuous duty.
  • Supply Voltages: 11-14 VDC for 12V models and 22-28 VDC for 24V models.
  • Operating Temperature: -40°C to +100°C.
  • Flow Rate: 3.6 liters per minute at 1.5 bar.
  • Max Working Pressure: 4.5 bar on the injection pump.
  • Weight: 1 kg.
  • Vibration Test: 20 G, 50-500 Hz on three axes for 1 hour per axis.
Certifications: The valve complies with European Standards EN50082-1, EN50082-2, EN50081-1, and EN50081-2.
Installation Instructions:
  • The valve should be installed on a rigid, flat surface close to the injection pump, ideally within 200 mm.
  • Use the provided screws with a torque of 11-12 Nm.
  • Flexible hoses are recommended for connections; if rigid pipes are used, ensure perfect alignment to avoid valve distortion.
  • Use sealing washers (14.3x1.5 mm) with a torque of 30-35 Nm for steel or aluminum, and 35-40 Nm for annealed copper.
  • Ensure no air remains in the pipes post-installation.
  • A fuel filter and a check valve on the return pipe to the tank are recommended.
Operational Modes:
  • E.T.R. Mode: The engine starts when the valve is energized. De-energizing the valve stops the engine quickly, keeping the pipes filled with fuel for the next start.
  • E.T.S. Mode: The engine starts when the valve is de-energized. Energizing the valve stops the engine quickly, also keeping the pipes filled with fuel.
Additional Information: The valve's dual stopping system is achieved by inverting the solenoid valve. A 3/8” rubber pipe fittings kit is available (P/N CEI 111105).

SOLENOID VALVES FOR DIESEL ENGINES-1

Run-Stop Valve G4 ELETTROVALVOLA DISTRIBUTRICE A 4 VIE FOUR-WAY SOLENOID SLIDE VALVE E’ una elettrovalvola distributrice a 4 VIE per l'arresto e l'avvio rapido dei motori, per funzioni in DISECCITAZIONE (Energized to Run - E.T.R.) e in ECCITAZIONE (Energized to Stop - E.T.S.). Nella fase di fermata del motore utilizza la depressione in aspirazione della pompa di alimentazione per aspirare combustibile dalla pompa di iniezione. This is a four-way solenoid slide valve for fast engine ignition and shutdown, having both an E.T.R. (Energized To Run) mode and an E.T.S. (Energized To Stop) mode operation. During engine shutdown, the suction from the fuel supply pump is used to withdraw fuel from the injection pump. Vedi schema per E.T.R. e schema per E.T.S.

SOLENOID VALVES FOR DIESEL ENGINES-3

ISTRUZIONI PER L’INSTALLAZIONE L'applicazione sui motori é semplice e versatile perché il duplice sistema di fermata E.T.R. ed E.T.S. si ottiene invertendo la stessa elettrovalvola. L'elettrovalvola deve essere installata su una superficie rigida e piana il più vicino possibile alla pompa di iniezione. La distanza ottimale non dovrebbe superare i 200 mm. Usare le viti in dotazione (coppia di serraggio 11-12 Nm). Per la connessione della elettrovalvola è preferibile l'uso di tubi flessibili. Nel caso si dovessero utilizzare dei tubi rigidi é indispensabile curare il loro perfetto allineamento...
