GLOBAL SERIES Wet Type Magnetic Solenoid Valve SS and SA Series G01-31 Design Recognized by Overseas Safety Standards

In Pursuit of Safety (conforms to overseas standards) and Easy Use Conformance to Global Standards CE-, UL- and CSA-recognized You can depend on solenoid valves of NACHI brand. Recognized by reliable overseas safety standards such as CE (Europe), UL (U.S.A.) and CSA (Canada). Interchangeable with Conventional Products (30 designs) The valve proper as well as such parts as a centralized terminal box and coil are interchangeable with the conventional ones in terms of a kit. Features 1. Easy use 2. Low power consumption An expanded wiring space ensures easy wiring. Use of a 4-pin M12-connector (IEC60947-5-2) permits one-touch connection of wires. (Compatible with special parts) Redesigned terminal box improves waterproof properties. The power consumption of the DC solenoid (D※ and E※) is reduced, with high voltage and heavy current kept unchanged. This will further promote your energy saving policy. 3. Reliable switching An innovative fluid reaction compensating mechanism assures reliable valve switching. (Patent pending) Pursuit of safety Improved water proof properties The terminal block has been modified to improve the insulation performance. (Conforms to overseas standards) The packing is designed to be mated with the plate groove. Improved setscrews The setscrews are not disengaged even if they are excessively loosened. Available M12 connector makes wiring simple. More convenient due to effective use of "Name Plate Installation Hole" You can fix the work instruction nameplate directly. You can place the plate there temporarily during wiring work. This will prevent the plate from being lost. Improved shape of cable entrance The cable entrance slope has been made less sharp to ensure easy cable connection. 1 Improved legibility of nameplate

Handling zTo make an effective use of the wet type solenoid valve, connect the pipe so that the T(R) port is always filled with oil. Do not plug the T(R) port. xTake appropriate measures to ensure that abnormal surge pressure in excess of the maximum permissible backpressure does not occur to the T(R) port. cPlease note that the maximum flow rate is subjected to restriction when you use a four-way valve as a two-way or one-way valve by blocking each port. vKeep the hydraulic oil clean at all times. (Level of contamination: equal to or better than NAS 12 class) bUse the petroleum based hydraulic oil conforming to Class 1 or 2 according to JIS K2213. nWater or glycol based hydraulic oil can be used for the standard valve. In this case, pressure must not exceed 31.5 MPa; further the flow rate must not exceed 80 % of the maximum flow rate. If you want to use other flame resistant hydraulic oil, please contact us for detailed information and precautions. mTake care that the permissible voltage range is not exceeded. ,Turn on the AC solenoid after you have installed the coil on the valve. .Connect a drain pipe to the T(R) port of the valve for operation symbols 2X, H2X and E2X. 0If the product is kept at the switched position for a long time at a high pressure, operation failure may occur due to sticking of fluid. When it must be kept at the switched position for a long time at a high pressure, contact us for further information. 1When you use a detent type valve (E2X, E3X, E3Z), keep power turned on in order to keep the switched position without fail. 2It should be noted that the manual pin operating force is changed by tank line back pressure. 3If you use the valve with power kept turned on, the coil surface temperature will rise. So determine the valve installation position to ensure that your hand will not touch the heated position.

Option (Description of Auxiliary Symbols) Shock-less Type (Type symbol: F) Surge-less type (Type symbol: G) Switching response characteristics Indicates the pressure waveform of valves in the hydraulic circuit given in the following sketch. In the dry type valve, a big impact (noise) or pipe vibration will occur due to sudden pressure drop or rise caused by open/close operation of the valve. In the shock-less solenoid valve, however, there is no pressure change due to open/close operation of the valve. Accordingly, there is no impact (noise) or pipe vibration when the valve is switched. φ 63 φ 35 300 Indicates the surge voltage waveform when the power supply of the DC solenoid valve is turned on or off by a relay.
