2 Hydraulic Fluids Fluid Types Any type of hydraulic fluids listed in the table below can be used. Petroleum base oils Synthetic fluids Water containing fluids Use fluids equivalent to ISO VG or VG. Use phosphate ester or polyol ester fluid. When phosphate ester fluid is used, prefix "F-" to the model number because the special seals (fluororubber) are required to be used. Use water-glycol fluid. Note: For use with hydraulic fluids other than those listed above, please consult your Yuken representatives in advance. Recommended Viscosity and Oil Temperatures Use hydraulic fluids which satisfy the recommended viscosity and oil temperatures given below.

Please maintain the degree of contamination within NAS 8-Grade. Use 5 µm or finer line filter. 7 Flow Controls

3 FLOW CONTROLS Flow Control Valves / Flow Control and Check Valves These valves are pressure and temperature compensating type valves and maintain a constant flow rate independent of change in system pressure (load) and temperature (viscosity of the fluid). They control flow rate of the hydraulic circuit and eventually control speed of the actuator precisely. Valves with an integral check valve allow a controlled flow and reverse free flow. Repeated resetting can be made easily with a digital readout.

Instructions Min. required pressure difference The minimum differential pressure between inlet and outlet port is required to obtain the optimum pressure compensation. It varies according to the flow rate to be set. For details, please refer to the performance curves. Free flow Check valve pressure drops vary with flow rates. If models with check valves are used, see free flow pressure drop characteristics. Flow adjustment [F * G-] Loosen the locking screw and turn the flow adjustment dial clockwise for increase, and anti-clockwise for decrease. The dial makes about revolutions from zero to full flow and the valve opening is indicated on the revolution indicator. (Refer to characteristics of "Metred Flow vs. ial Position"). After flow adjustments, tighten the locking screw. [F * G-,,, ] Loosen the locking screw and turn the flow adjustment handle clockwise for increase, and anti-clockwise for decrease.

15 FLOW CONTROLS Pilot Operated Flow Control Valves / Pilot Operated Flow Control and Check Valves Flow control of these valves is continuously made by a hydraulically operated pilot piston mechanism which controls opening area of the orifice of the valve. With the use of these valves, shockless operation either in acceleratio or deceleration can be obtained. With the compensator for the pressure and temperature, stable flow control can be obtained regardless of the changes in the pressure (load) and temperature (oil viscosity). T Graphic Symbols T Max.

25 FLOW CONTROLS Restrictors / One Way Restrictors This valve is used to regulate an actuator speed in a circuit where line pressure is almost steady and small fluctuation of oil flow due to pressure changes is permitted. Integrated check valve allows reversed free flow from outlet to inlet port. Pressure balanced construction provides less effort in adjustment at high pressure.

Flow rate through the valve is regulated by the movement of the spool, which is operated by a cam. When the spool is depressed, the flow is decreased in Normally Open type valves and increased in Normally Closed type valves.

44 These valves are the combination of flow control valve, a deceleration valve and a check valve and used mainly for controlling rapid traverse and feed cycles machine tools. Switching from rapid traverse to feed is made by a cam operation, and fine feed control is accomplished by dial rotation regardless of pressure and oil temperature variation. Rapid return is free of cam actuation. Specifications UC---A- - UC---B- - UC---C- - UC--8-A- - UC--8-B- - UC--8-C- - UC--- - UC UC--- - UC UC--- UC--- Max. Flow (U.S.GPM) [] (. [.]) [8] (.
