Frequently Asked Questions
Q1: Is this a simple throttle / needle valve?
No. A simple throttle valve (only orifice) lets flow vary with pressure difference. The 2FRM is a pressure-compensated flow control valve — the built-in pressure compensator (spool) keeps the set flow rate essentially constant despite changes in load pressure or supply pressure (within its compensation range ~15-300 bar ΔP across compensator).
Q2: What does "B36 /32QRV" mean?
- B36 = NG6 sandwich, rotary knurled knob with scale (0-max) + locking setscrew — adjustable by hand
- /32 = maximum adjustable flow = 32 L/min
- 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 (if tightened), turn the knurled knob clockwise to increase flow, counterclockwise to decrease. The knob has a scale (1-10 or % reference — not in L/min directly). Use a flow meter to correlate the scale to actual L/min for your application. 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 as ZDR/Z2FS sandwiches. Uses NG6 DIN 24340 Form C / ISO 6263 bolt pattern (4× M5). Observe the directional arrow on the valve body — A→B = controlled flow.
Q5: Does it work both ways?
No — one direction is pressure-compensated metered flow (A →B), the opposite direction (B→A) is free return through the check valve (no flow control, minimal pressure drop ~0.5 bar). For bidirectional flow control you need two 2FRM valves or a 4-way flow control solution.
Q6: Common faults & causes?
- Flow varies with load pressure: pressure compensator spool stuck (contamination) — check oil filtration (ISO 4406 18/16/13 or better); or system pressure too low to generate required ΔP across compensator (<~15 bar)
- No flow / very low flow even at max knob: valve installed backwards (reverse arrow), or compensator spool jammed
- Cannot reach max flow / flow unstable: wrong model (smaller Qmax), partially closed, or excessive viscosity (cold start) — allow warm-up
- Excessive heat: some pressure drop is normal; if the valve is set for very low flow but sees high ΔP, energy dissipates as heat — this is normal for flow controls
Q7: Minimum pressure requirement?
The pressure compensator typically needs min. ~15 bar differential pressure across the compensator to properly regulate. System supply pressure must exceed the highest load pressure + ~15-20 bar + line losses for accurate flow control.
Q8: Fluid & seal compatibility?
NBR seals = mineral oil (HL/HLP) & HFC (water-glycol). For HEES/HETG biodegradable oils or HFD phosphate ester → specify FKM (Viton) seal variant. Maintain oil cleanliness per ISO 4406 code 18/16/13 or better.
