1 IRCTIONAL CONTROLS The Yuken Multi-Purpose Valves Comply with The Needs of Reducing Cost and Size of Your Machine YUKN's Multi Purpose Valve s are compound valves composed of the main valve having four poppets, / Solenoid Operated irectional Valves for pilot and Pilot Selector Valves. This valve is multifunctionalized by having individual poppet had functions such as directional control, flow control or pressure control according to the combination of the main valve and pilot selector valve. Features Multi-purpose control valves The valves combine three functions of directional control, flow control and of pilot operated check valve (or counterbalance valve). The valves contribute for reducing a number of valves in applications and space for installation and then eventually leads to reduction in size and cost of your machines. Quick response, High reliability Changeover response time is very quick as the valves are poppet type, there is no over-lap. No hydraulic lock occurs as there is no leakage of pressurised oil from the seat parts. asy to reduce shock in your hydraulic system By selecting proper diameter of orifice for pilot, the open/close timing of the flow passage can be set freely. Therefore, smooth starting and stopping of actuator can be done combined with using shockless type poppet. Noise of ON/OFF and vibration of piping in hydraulic system can be also reduced. For regenerative circuit position- way type, which is to compose regenerative circuit, is available. By adopting regenerative circuit, gaining fast feed speed by using smaller volume pump is possible. Therefore saving electric power of system is possible. The mounting dimensions are conformed with ISO standard The valves are interchangeable with our conventional valves in mounting.

5 IRCTIONAL CONTROLS Instructions Pilot Pressure Pilot pressure of external pilot drain models must always exceed the pressure of the main pressure port "P". Pilot rain Port Avoid connecting the pilot drain port to a line with possible surge pressure. rain Connection when with Counterbalance Function When a valve having counterbalance function is used with internal drain type, the counterbalance pilot valve is subjected to pressure fluctuation and the pressure setting becomes unstable. For this reason, be sure to use external drain type valve. Flow Adjustment To perform the flow adjustment, loosen the lock nut, then turn the flow adjustment screw clockwise to decrease the flow. Be sure to re-tighten the lock nut after the adjustment. Pressure Adjustment To perform the pressure adjustment, loosen the lock nut, then turn the pressure adjustment screw clockwise to increase the pressure. Be sure to re-tighten the lock nut after the adjustment.

21 IRCTIONAL CONTROLS How to Change Pilot & rain Connection Pilot Connectio n and rain Connectio n can be changed easily with a disconnection/connectio n of pilot plug. The following drawings give illustrations of xternal Pilot-xternal rain Type, When changing to Internal Pilot-Internal rain Type, the following procedure may be followed. xternal Pilot Internal Pilot (See Section -) ) Remove pipe plug. ) Remove pipe plug. ) Wind a sealing tape around the pipe plug the port., then fit the plug into xternal rain Internal rain (See Section -) ) Remove pipe plug. ) Remove pipe plug. ) Wind a sealing tape around the pipe plug, then fit the plug into the port. ) In case of SLHG-, fit the plug into the port "Y" on the sub-plate. In case of SLHG-6/, wind a sealing tape around the plug and then thread it into the port "Y".
