17 Installation Information Series D1V Fluid Recommendations remium quality hydraulic oil with a viscosity range between cst. ( SSU) at 38 C (100 F) is recommended. he absolute operation viscosity range is from cst. ( SSU). Oil should have maimum anti-wear properties and rust and oidation treatments. Fluids and Seals Valves using synthetic, fire-resistant fluids require special seals. When phosphate ester or its blends are used, FLUOROCRON seals are required. Waterglycol, (95/5) water-in-oil emulsions, and petroleum oil may be used with NIRILE seals. emperature Recommendation Recommended oil temperature: -29 C to +71 C (-20 F to +160 F) Filtration For maimum valve and system component life, the system should be protected at a contamination level not to eceed 125 particles greater than 10 microns per milliliter of fluid. (SE Class 4 or better, ISO 16/13). ank Line Surges If several valves are piped with a common tank line, flow surges in the line may cause unepected spool shift. Detent style valves are most susceptible to this. Separate tank lines should be used when line surges are epected in an application. Recommended Mounting osition Valve ype Detent (Solenoid) Spring Centered Spring Offset Recommended Mounting osition Horizontal Unrestricted Unrestricted Silting Silting can cause any sliding spool valve to stick and not spring return, if held shifted under pressure for long periods of time. he valve should be cycled periodically to prevent sticking. Single ass Operation Valve flow ratings are for double pass operation (with equal flow in both paths). When using these components in single pass applications, flow capabilities may be reduced. Consult your local arker representative for details. Flow ath Data D1V Operator Operator *Note: On valves with 008 or 009 spool, and/or operators reverse sides. Flow paths remain the same as viewed from top of valve. Double Solenoid. With solenoid energized, flow path is and. When solenoid is energized, flow path is and. he center condition on a spring-centered valve eists when both coils are de-energized, or during a complete shift, as the spool passes through center. Detent and Spring Offset. he center condition eists on detent and spring offset valves only during spool crossover. o shift and hold a detented spool, only a momentary energizing of the solenoid is necessary. he minimum duration of the signal is approimately 0.1 seconds for DC voltages. his position will be held provided the spool center line is in a horizontal plane, and no shock or vibration is present to displace the spool. Single Solenoid. Spring offset valves can be ordered in styles, E, F, H, K and M. Flow path data for the various styles are described in the order chart. Electrical Failure Should electric power fail, 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 simultaneously, machine actuators may continue to function in an undesirable manner or sequence. orque Specifications orque values recommended for the bolts which mount the valve to the manifold or subplate are as follows: #10-24 thread (M5-0.8) torque 5.6 Nm (50 in-lbs) p65, dd 40 arker Hannifin Corporation Elyria, Ohio, US
