Q1: Is this a hydraulic lock / pilot check valve (double block-and-bleed)?
No. A hydraulic lock / pilot-operated check valve is Rexroth type SV / SL. This item (2FRM6) is a pressure-compensated flow control valve — it meters flow in one direction and allows free return in the other. It does not lock a cylinder in position.
Q2: What does "/1.5QRV" and "B36" mean?
B36 = NG6 sandwich, rotary knurled knob with scale (0–max) + locking setscrew — adjustable by hand.
/1.5 = maximum adjustable flow = 1.5 L/min (very fine metering — used for creep-speed, pilot supply, or small actuator feed).
Q = flow controlled in A→B direction.
R = free reverse flow B→A via check valve.
V = NBR seals (standard).
Q3: How do I set the flow?
Loosen the lock setscrew, turn the knurled knob clockwise to increase flow, counterclockwise to decrease. The knob has a relative scale — use a flow meter to calibrate against actual L/min. Retighten the lock setscrew after setting.
Q4: How is it mounted?
As a sandwich (stackable) valve between a directional control valve and the NG6 subplate, same bolt pattern as ZDR/Z2FS sandwiches (4× M5). Observe the arrow on the valve body — A→B = controlled/metered flow, B→A = free return.
Q5: Does it compensate for load pressure changes?
Yes — the integrated pressure compensator (spool) keeps the set flow essentially constant despite changes in load (downstream) pressure or supply pressure fluctuations, provided system pressure ≥ load pressure + ~15–20 bar ΔP across the compensator.
Q6: Common faults & causes?
Flow varies with load: compensator spool stuck (contamination) — check oil filtration (ISO 4406 18/16/13 or better); or insufficient ΔP across compensator (<15 bar).
No / very low flow at max knob: valve installed backwards, or compensator/spool jammed from dirt.
Cannot reach 1.5 L/min or flow unstable: partially clogged orifice (very small at low flows — fine filtration critical), excessive viscosity (cold start).
Excessive heat: normal for flow controls — pressure drop × flow = heat; ensure system pressure isn't unnecessarily high above what load requires.
Q7: Looking for an actual hydraulic lock (pilot check / overcenter valve)?
You likely need Rexroth SV… (cartridge pilot check) or SL… (sandwich pilot check / dual pilot check) for cylinder locking — not the 2FRM series. Let me know if you need that instead.
Q8: Fluid & seal compatibility?
NBR seals = mineral oil (HL/HLP) & HFC (water-glycol). For HEES/HETG bio-oils or HFD → specify FKM (Viton) seal variant.
