2 echnical Information General Description directional control valves are 5-chamber, pilot operated, solenoid controlled valves. hey are available in 2 or 3-position styles. hese valves are manifold or subplate mounted, and conform to NF s D10, CEO 10 mounting pattern. Operation pilot operated valves are standard with low shock spools and pilot orifice. he orifice can be removed if a faster shift is required. However, it is recommended that all systems operating above 138 ar (2000 SI) use the standard valve to avoid severe shock. Features Low pressure drop design. Hardened spools provide long life. Fast response option available. Wide variety of voltags and electrical connection options. Explosion proof availability. No tools required for coil removal.

20 Installation Information FOR MXIMUM VLVE RELIILIY, DHERE O HE FOLLOWING INSLLION INFORMION. he following is important installation information which applies to all directional control valves described in this catalog. Mounting osition Detent Horizontal Spring Offset Unrestricted Spring Centered Unrestricted Fluid Recommendations remium quality hydraulic oil with a viscosity range between cst ( SSU) t 38 C (100 F) is recommended. he absolute operating viscosity range is from cst ( SSU). Oil should have maximum anti-wear properties and rust and oxidation treatment., D10 Silting Silting can cause any sliding spool valve to stick and not spring return if held under pressure for long periods of time. he valve should be cycled periodically to prevent sticking. Special Installations Consult your arker representative for any application requiring the following: ressure above rating. Fluid other than those specified. Oil temperature above 71.1 C (160 F). Flow path other than normal. Mounting atterns Series NF Size D101V*, D10 D10 1-1/4 Fluids and Seals Valves using synthetic, fire-resistant fluids require special seals. When phosphate esters or its blends are used, FLUOROCRON seals are required. Waterglycol, water-in-oil emulsions and petroleum oil may be used with SNDRD seals. orque Specifications he recommended torque values for the bolts which mount the valve to the manifold or subplate are as follows: Nm (300 ft-lbs). Filtration For maximum valve and system component life, the system should be protected from contamination at a level not to exceed 125 particles greater than 10 microns per milliliter of fluid (SE class 4/ISO 16/13). 207 Elyria, Ohio, US

21 Installation Information W, D101V, D101VL ank and Drain Line Surges If several valves are piped with a common tank or drain line, flow surges in the line may cause an unexpected spool shift. Detent style valves are most susceptible to this. Separate tank and drain lines should be piped in installations where line surges are expected. Electrical Characteristics (Detented Spool) Only a momentary energizing of the solenoid is necessary to shift and hold a detented spool. Minimum duration of the signal is 0.1 seconds for DC voltages. For C voltages the response time is 0.06 seconds. Spool position will be held provided the spool centerline is in a horizontal plane, and not shock or vibration is present to displace the spool. Electrical Failure or Loss of ilot ressure (D101V) Should electric power fail or loss of pilot pressure occur, spring offset and spring centered valves will shift to the spring held position. Detented valves will stay in the last position held before power failure. If main flow does not fail or stop at the same time power fails, machine actuators may continue to function in an undesirable manner or sequence. ilot/drain Characteristics ilot ressure: 4.4 to 207 ar (65 to 3000 SI) External: n oil source sufficient to maintain minimum pilot pressure must be connected to the X port of the main body. When using the external pilot variation, a 1/16" pipe plug must be present in the main body pilot passage. (For details see Dimension pages.) his plug will be furnished in valves ordered with pilot code 2, 3, 5 or 6. Internal: Flow is internally ported from the pressure port of the main valve body to the port of the pilot valve. he pressure developed at the port of the pilot valve must be 4.4 ar (65 SI) minimum at all times. Integral Check: Valves using internal pilot and internal drain with an open center spool (spools 2, 7, 8 & 9) can be ordered with an integral check valve in the pressure port of the main valve codes 3 & 6. ilot oil will be internally ported from the upstream side of this check to the port of the pilot valve, ensuring sufficient pilot pressure. 1/16 pipe plug will be present in the main body. he X port in the subplate must be plugged when using the integral check. ilot Valve Drain: Maximum pressure 102 ar (1500 SI) C standard, 207 ar (3000 SI) C optional/dc standard. External: When using an external drain, a 10 x 24 x 0.31 long set screw must be present in the main body drain passage. (For details see Dimension pages.) his plug will be furnished in valves ordered with drain code 1, 2 or 3. Drain flow from the pilot valve is at the Y port of the main body and must be piped directly to tank. Maximum drain line pressure is 102 ar (1500 SI) C standard, 207 ar (3000 SI) C optional/dc standard. ny drain line back pressure is additive to the pilot pressure requirement. Internal: Drain flow from the pilot valve is internally connected to the main valve tank port. ank and drain pressure are then identical so tank line pressure should not exceed 102 ar (1500 SI) C standard, 207 ar (3000 SI) DC standard/c optional. ny tank line back pressure is also additive to the pilot pressure requirement. If flow surges (a cause of pressure surges) are anticipated in the tank line, an external drain variation is recommended. he Y port in the subplate must be plugged when using an internal drain.

22 Installation Information Series D10 ank and Drain Line Surges If several valves are piped with a common tank or drain line, flow surges in the line may cause an unexpected spool shift. Detent style valves are most susceptible to this. Separate tank and drain lines should be piped in installations where line surges are expected. Loss of ilot ressure Should a loss of pilot pressure occur, spring offset and spring centered valves will shift to the spring held position. No spring valves will stay in the last position held. If main hydraulic flow does simultaneously stop, machine actuators may continue to function in an undesirable manner or sequence. ilot Drain Characteristics ilot ressure: 4.4 to 207 ar (65 to 3000 SI) Direct pilot operated valves use the X and Y ports to supply pilot oil directly to the ends of the spool, providing spool shifting force. block mounted on top of the valve body is internally cored to make the necessary connections. hus when X is pressurized, Y is used as a drain; and when Y is pressurized, X becomes the drain. ny back pressure in these lines when they are being used as a drain is additive to the pilot pressure requirement. Internal Drain: On spring offset models, only the X port is pressurized, as the spring returns the spool to its at rest position. On these models, Y may be internally drained through the main tank passage in the valve.
