12 E SERIES PRESSURE CONTROL VALVES Pilot Relief / Relief / Reducing and Relieving Instructions Mounting Be sure that the air vent faces up. In addition, if the valve is mounted vertically, the minimum adjustment pressure is (9 PSI) or higher. [Good example] [Bad example] SOL SOL SOL Air Bleeding To ensure stable control, bleed the air from solenoid completely and fill its core with oil. Bleeding can be done by slowly loosening one of the air vents at the end of the solenoid. Choose one of the three air vents which is expected to work most effectively (see the figure to the right). Manual Adjustment Screw When initial adjustments are to be made or when no current is supplied to the valve due to electrical failure or other problem, turn the manual pressure adjustment screw to temporarily set the valve pressure. In that case, when turn the manual pressure adjustment screw clockwise, the valve pressure rises. Under normal condition, however, this screw must be kept in its original position (see the figure to the right). Places Solenoid Manual Pressure Adj. Screw Ω Series Solenoid Tank and Drain Piping The tank-line back pressure and drain back pressure directly affect the minimum adjustment pressure. Therefore, do not connect the tank or drain pipes to other lines, but connect them directly to the reservoir maintaining the back pressure as low as possible. Be sure that the tank and drain pipe ends are immersed in fluid. ysteresis and Repeatability Value Indications The hysteresis and repeatability values indicated in the specifications for each control valve are determined under the following conditions: ysteresis Value: Obtained when Yuken's applicable power amplifier is used.

40 E SERIES FLOW Flow Control / Flow Control and Check / Flow Control and Relief General Information Up to. ( PSI), L /m in ( U.S.GPM) Pub. EC- Flow Control / Flow Control and Check Valves These valves vary their output flow proportionally to an input current, therefore, by controlling the input current from the power amplifier, the flow rate in the system can be continuously, remotely and optionally regulated. Furthermore, as the valves have the functions of pressure and temperature compensation, the flow rate is not affected by the variation in the pressure (load) and temperature (viscosity of hydraulic fluids). These valves are optimal for such a usage where the start-up, stop and speed change of the actuator are required to be done without shocks. The valves are used together with the applicable power amplifiers. Ω Series... Ω Series... Page Page A direct-acting model designed to control the throttle A hydraulic pilot amplification model is employed, with a high-power solenoid is employed, providing a achieving a small hysteresis with a small solenoid. high strength against contamination in oil and an outstanding reliability. O M O M Flow Control and Relief Valves These valves control the pump pressure effectively by responding to a small pressure difference against the load pressure. Therefore, it can be said that they are energy-saving metre-in type flow control valves which can be operated at a low power consumption.

Petroleum Base Oils Use fluids equivalent to ISO VG or VG 6. Use phosphate ester or polyol ester fluids. When phosphate ester fluid is used, prefix "F-" Synthetic Fluids to the model number because the special seals (fluororubber) are required to be used. Water-Containing FluidsUse water-glycol fluid. Note:For use with hy draulic fluids other than those listed above, please consult y our Yuken representatives in advance. Recommended Fluid Viscosity and Temperature Use hydraulic fluids which satisfy the both recommended viscosity and oil temperatures given in the table below. Name Viscosity Temperature Flow Control Valves - mm /s Flow Control and Check Valves Flow Control and Relief Valves (98-9 SSU) C ( - 6 F) Control of Contamination Due caution must be paid to maintaining control over contamination of the hydraulic fluids which may otherwise lead to breakdowns and shorten the life of the valve.

42 E SERIES Flow Control Valves Flow Control / Flow Control and Check / Flow Control and Relief Instructions Mounting Positioning Orientation Be sure that the air vent faces up. The air vent position can be changed as desired. If the pressure control solenoid of the EFBG valve is mounted vertically, the minimum adjustment pressure is (9 PSI) or higher. [Good example] [Bad example] SOL SOL SOL Air Bleeding To ensure stable control, bleed the air from solenoid completely and fill its iron core with oil. Bleeding can be done by slowly loosening an air vent. The Ω series solenoid has three air vents. Choose one that appears most helpful (see the figure below). Solenoid Places Solenoid Case Manual Adjustment Screw When initial adjustments are to be made or when no current is supplied to the valve due to electrical failure or other problem, turn the manual adjustment screw to temporarily set the valve pressure and flow rate. In that case, when turn the manual adjustment screw clockwise, the valve pressure rises and flow increase. Under normal conditions, however, this screw must be kept in its original position (see the figure below). Manual Pressure Adj. Screw or Manual Flow Adj. Screw Ω Series Solenoid M Screw Manual adjustment pin Manual adjustments can be done by screwing for example an M L screw in the M thread or pushing in a pin there with a rod etc. Ω Series Solenoid Tank and Drain Piping The tank-line back pressure and drain back pressure directly affect the minimum adjustment pressure or flow adjustment valve main spool operating force. Therefore, do not connect the tank or drain pipes to other lines, but connect them directly to the reservoir maintaining the back pressure as low as possible. Be sure that the tank and drain pipe ends are immersed in fluid. ysteresis and Repeatability Value Indications The hysteresis and repeatability values indicated in the specifications for each control valve are determined under the following conditions: ysteresis Value: Obtained when Yuken's applicable power amplifier is used. Repeatability Value: Obtained when Yuken's applicable power amplifier is used under the same conditions. No.

Instructions Drain Back Pressure Check that the drain back pressure dose not exceed. (9 PSI). When Relief Valve Passing is Low in Pressure Control State To avoid preselected pressure instability, use a passing flow rate of L/min (.6 U.S.GPM) or higher for nominal sizes and 6 or L/min (. U.S.GPM) or higher for nominal size. Further, check that the tank-line back pressure does not exceed. (7 PSI). Safety Valve Pressure Setting The pressure of the safety valve is preset at the value equal to the upper limit of the pressure adjustment range plus (9 PSI). Please adjust the pressure of the valve so preset to meet the pressure to be used actually. To lower the pressure setting, turn the safety valve pressure adjustment screw anti-clockwise. After adjustment, be sure to tighten the lock nut. No.

Instructions Drain Back Pressure Check that the drain back pressure dose not exceed. (9 PSI). When Relief Valve Passing is Low in Pressure Control State To avoid preselected pressure instability, use a passing flow rate of L/min (. U.S.GPM) or higher. Further, check that the tank-line back pressure dose not exceed. (7 PSI). Safety Valve Pressure Setting The pressure of the safety valve is preset at the value equal to the upper limit of the pressure adjustment range plus (9 PSI). Please adjust the pressure of the valve so preset to meet the pressure to be used actually. To lower the pressure setting, turn the safety valve pressure adjustment screw anti-clockwise. After adjustment, be sure to tighten the lock nut.

91 E SERIES DIRECTIONAL AND FLOW CONTROL VALVES EDFG-//6 (/8,/,/) Mounting General Information Up to. ( PSI), 8 L/min (7. U.S.GPM) Pub. EC- These valves are double-deck directional and flow control valves employing as their pilot the electro-hydraulic proportional pressure reducing valves with two proportional solenoids. The flow rate can be controlled by changing an input current to the solenoids and the direction of the flow can be controlled by providing the current to either solenoid of the two. By combining the valves with the power amplifiers specially designed for the valves, the speed control, acceleration, deceleration and directional control can be done with a single valve, which eventually makes the hydraulic circuits simple and contributes the cost of the hydraulic systems. a A B b P T Y X ydraulic Fluids Fluid Types Any type of hydraulic fluid listed in the table below can be used. Petroleum base oils Synthetic Fluids Water Containing Fluids Use fluids equivalent to ISO VG or VG 6. 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 Fluid Viscosity and Temperature Use hydraulic fluids which satisfy the both recommended viscosity and oil temperatures given in the table below. Viscosity - mm /s (98-8 SSU) Temperature - +6 C ( - F) Control of Contamination Due caution must be paid to maintaining control over contamination of the hydraulic fluids which may otherwise lead to breakdowns and shorten the life of the valve. Please maintain the degree of contamination within NAS 68-Grade. Use μm or finer line filter. No.

[Good example] SOL a SOL b [Bad example] SOL a SOL b Air Bleeding To ensure stable control, bleed the air form solenoid completely and fill its icon core with oil. For this purpose, it is recommended to provide the drain line with a check valve having a cracking pressure of about. (.8 PSI). Bleeding can be done by slowly loosening an air vent. There are three air vents. Chose one that appears most helpful (see the figure below). In addition, be sure to extend the end of the drain line into the oil. Manual Adjustment In the event of an electric fault or emergency, a manual shift can be made by screwing in the manual adjustment screw. Take care, however, that this manual shift has no flows adjusting function. For this operation, set the pilot pressure (or P-port pressure on an internal-pilot model) below 7 ( PSI). After operation, be sure to return the manual adjust-ment screw completely to the original position (see the figure right). Places Solenoid Manual Adj. Screw Ω Series Solenoid No.

102 POWER AMPLIFIERS / SETTING ADJUSTERS FOR ELECTRO- YDRAULIC CONTROL VALVES Setting Adjusters The setting adjuster supplies the command signal voltage to the power amplifier. Since the setting adjuster is closely related to actual machine operating procedure, the user generally provides this device. Yuken makes the following standard setting adjusters for general use and designs and manufactures special setting adjusters to order: Ty pe Function Page Manually Operated Setting Adjuster MC- MC- This is the sim plest setting adj uster, consisting of a trim m er ( k Ω) and a dial. Consisting of a centre-tapped trimmer ( k Ω- k Ω) and a dial, this setting adjuster is ideal for a servo system point Setting Adjuster AMC-V6-S- - Six trimmers are incorporated, so it is possible to set six points. 9 Multifunction Slope Controller AMC-T- This m ultifunction slope controller generates any desired -channel analog voltage pattern outputs. It can also be used with slope-proportional and timeproportional sy stems. Instructions for Pow er Amplifiers The power amplifiers should be kept away from hot and humid conditions which may deteriorate some components of the power amplifiers. They also should be installed in the clean and dry place where the vibration is minimal. Please avoid to install the power amplifiers in the complete enclosure or get them enclosed totally as they need to radiate the heat from semiconductors or ICs inside. Please use shielded wires for input signal transmission to prevent the amplifiers from any interference such as noise from outside. No.
