Directional Control Valves Series D1M
Bulletin 2544-B1/USA
Introduction Application
Features
Parker D1M Series hydraulic directional control valves are high performance, direct operated 4-way valves. They are available in 2 or 3 position styles. They are manifold mounted valves, which conform to NFPA’s D03 mounting pattern. These valves were designed for mobile hydraulic applications which require high cycle rates, long life and high efficiency.
• • • • • • •
Operation Parker’s D1M Series directional control valves consist of a four chamber style body, and a case hardened sliding spool. The spool is directly shifted by solenoid operators.

Flow
Example: Determine the maximum allowable flow of a D1M Series valve (#30 spool) at 83 Bar (1200 PSI) supply pressure. Locate the curve marked “30”. At 83 Bar (1200 PSI) supply pressure, the maximum flow is 30 L/M (8 GPM). At 241 Bar (3500 PSI), the flow is 28 L/M (7.5 GPM)
Important Notes for Switching Limit Charts 1. Shift limits charted for equal flow A and B ports. Unequal A and B port flows may reduce shift limits.

Installation Information Fluid Recommendations
Flow Path Data
Premium quality hydraulic oil with a viscosity range between 150-250 SSU (32 -54 cst) at 38° C (100°F) is recommended. The absolute operation viscosity range is from 80-1000 SSU (16-220 cst). Oil should have maximum anti-wear properties and rust and oxidation treatments.
D1M
Locating pin
P
Operator A
Operator B A
B T
*Note: On valves with 9 spool, A and/or B operators reverse sides. Flow paths remain the same as viewed from top of valve.
Fluids and Seals Valves using synthetic, fire-resistant fluids require special seals. When phospate ester or its blends are used, FLUOROCARBON seals are required. Waterglycol, water-in-oil emulsions, and petroleum oil may be used with NITRILE seals.
Double Solenoid. With solenoid “A” energized, flow path is P to A and B to T. When solenoid “B” is energized, flow path is P to B and A to T. The center condition on a spring-centered valve exists when both coils are de-energized, or during a complete shift, as the spool passes through center.
Temperature Recommendation Recommended oil temperature: -7° to +71°C (-20 to +160°F)
Single Solenoid. Spring offset valves can be ordered in four styles: B, E, H and K. Flow path data for the various styles are described in the order chart.
Filtration
Electrical Failure
For maximum valve and system component life, the system should be protected at a contamination level not to exceed 125 particles greater than 10 microns per milliliter of fluid. (SAE Class 4 or better, ISO Code 16/13).
Should electric power fail, spring offset and spring centered valves will shift to the spring held position. If main flow does not fail or stop simultaneously, machine actuators may continue to function in an undesirable manner or sequence.
Tank Line Surges Torque Specifications
If several valves are piped with a common tank line, flow surges in the line may cause unexpected spool shift. Detent style valves are most susceptible to this. Separate tank lines should be used when line surges are expected in an application.
Torque 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).
Recommended Mounting Position Valve Type

Spring Offset

Silting Silting can cause any sliding spool valve to stick and not spring return, if held shifted under pressure for long periods of time. The valve should be cycled periodically to prevent sticking.
Single Pass 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 Parker representative for details.
