2 Solenoid Operated irectional Valve G4V-3- esign 1. Product introduction and target applications G solenoid valves are used in hydraulic circuits to start, stop and direct flow. With electronics on board, the G4V3-Z- enables new machine control solutions, eliminating solenoid power shifting in the controls cabinet. The G4V3 series valve takes advantage of contemporary electronics and wiring practices applied in automation solutions world wide. Using industry standard M1 connectors and with the optional on board switching amplifier the series valve offers OEMs and users opportunity to simplify the electronics, and increase throughput by specifying preassembled and pre-wired electro-hydraulic manifold assemblies. This valve with on-board electronics has passed water immersion tests, qualified to IP, and EMC testing to CE requirements. The rugged construction, designed and qualified by Eaton with key features such as plug in coils, M1 connector and multiple coil wattages, meeting major automotive plant specifications, makes this valve a natural for global projects. This solenoid valve is the latest in a long line of recognized Eaton brand G valve series. The series valve builds on the proven series valve, adding connectivity and functionality tailored for state of the art 4 VC machine control system. This product is available from and supported by Eaton and an extensive network of qualified distribution partners world wide.. Functional description Electronics are housed in a robust metal housing sealed to IP environmental ratings and meeting CE standards for Electromagnetic Compliance. Standard features include surge suppression and LE s indicating voltage to the active coil. The Z option adds the switching amplifier on board, eliminating the cost and heat associated with having this function in the machine controls cabinet. 4 VC power is supplied separately to pin1 of the M1 connector, while pin or 4 control the solidstate switch connection to either solenoid A or B. Pin 3 is common. 3.

WARNING: Electromagnetic Compatibility (EMC) It is necessary to ensure that the valve is wired up in accordance with the connection arrangements shown in this leaflet. For effective protection, the user s electrical cabinet, the valve subplate or manifold and the cable screens should be connected to efficient ground points. In all cases, both valve and cable should be kept as far way as possible from any source of electromagnetic radiation such as cables carrying heavy current, relays and certain kinds of portable radio transmitters, etc. ifficult environments could mean that extra screening may be necessary to avoid interferance.
