R900410875 ZDR10DP2-5X/75YM Rexroth Germany Made Pressure Reducing Valve
Direct-acting, 3-way pressure reducing valve designed for sandwich mounting between directional control valves and NG10 subplates. Manufactured by Rexroth in Germany.
No. A relief valve (DB/DBD) limits upstream/system pressure; a pressure reducing valve (ZDR) maintains a lower, constant pressure in a downstream (secondary) circuit. If inlet (primary) pressure drops below the set reduced pressure, the ZDR opens fully and passes flow unregulated - it does not protect the pump from overpressure.
What does "DP2 /75YM" mean?
DP2 = NG10 sandwich, rotary hand knob with protective cap (hand-adjustable)
/75 = spring stage, max. adjustable reduced pressure = 75 bar (low-pressure stage; also available: /150, /210, /315)
Y = external pilot drain - pilot oil returns via separate Y-port to tank, not via the sandwich T-channel
M = FKM (Viton) seal material
How do I adjust the reduced pressure?
With the secondary circuit under flow, lift/remove the cap and turn the rotary knob clockwise to increase, counterclockwise to decrease. Verify with a pressure gauge at the secondary port - the knob has no calibrated scale. Factory preset is typically near minimum; fine-tune under operating flow if possible.
How is the valve mounted?
As a sandwich (stackable) valve between a directional control valve and the NG10 subplate. Uses NG10 DIN 24340 Form E / ISO 5781 bolt pattern (four M10 bolts). Sandwich port IDs: P = primary (high pressure from pump side), A (or B) = reduced secondary pressure to actuator, T = tank return, Y = external pilot drain to tank (must be plumbed separately!).
Why specify the "Y" (external drain) version?
If the T-line in the valve stack has >2-3 bar backpressure, an internally drained ZDR's set reduced pressure will increase by the amount of T-backpressure. The Y-version drains the pilot independently to tank, keeping the set reduced pressure stable. Always use Y-version if T-backpressure is present or uncertain.
What is the "M" seal version for?
M = FKM (Viton) seals - for:
Higher fluid temperature (up to ~90 °C)
Biodegradable oils (HEES, HETG - NBR not recommended)
Some HFC appliions (short-term; NBR preferred for prolonged HFC exposure)
Not for phosphate ester (HFD) unless specially confirmed.
Common faults & causes?
Reduced pressure too high / cannot lower: wrong spring stage (e.g. /210 or /315 installed), pilot orifice clogged, Y-drain line blocked (Y-version!), inlet pressure insufficient to allow regulation
Reduced pressure drifts / unstable: contaminated pilot seat, damaged O-ring on sandwich face causing internal leak, Y-line restricted or pinched
Excessive heating at T: Normal for 3-way ZDR - some bypass to T occurs to hold set pressure; excessive heat may indie stuck spool from contamination - flush system & verify filtration (ISO 4406 18/16/13 or better)
