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.
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.
As a sandwich (stackable) valve between a directional control valve and the NG6 subplate. Uses NG6 DIN 24340 Form E / ISO 5781 bolt pattern. 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).
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.
M = FKM (Viton) seals - for:
Not for phosphate ester (HFD) unless specially confirmed - standard NBR applies.
Standard ZDR6 sandwich reduces pressure in one working line (usually marked A on sandwich face). For independent A+B reduction use two ZDR6 valves or a custom manifold.
