|---|---|
| Full Part Number | R901508500 (IN001 = individual inspection suffix) |
| Base Model | 2FRM 6 - B76 - 2X / 10QRV |
| Valve Type | 2-way throttle check valve with pressure compensator (flow control - constant flow despite pressure fluctuations) |
| Nominal Size (NG) | 6 - sandwich mounting per ISO 6263 / NG6 (DIN 24340 Form C) |
| Function | Adjustable orifice + pressure-compensated spool → constant flow A→B; free reverse flow B→A via check valve |
| Adjustment Type | B76 = Rotary knurled knob with scale & tamper-lockable/sealable cap (hand-adjustable; same performance as B36) |
| Component Series | 2X (series 20+, dimensionally interchangeable) |
| Max. Adjustable Flow | 10 L/min (Q range typically 0.2-10 L/min) |
| Max. Operating Pressure | 315 bar (ports A & B) |
| Cracking Pressure (Reverse Check) | approx. 0.5 bar (standard free-return) |
| Mounting Pattern | NG6 sandwich (4× M5 bolts), between directional valve & subplate |
| Seal Material | NBR (standard, code V - for mineral oil HL/HLP, HFC) |
| Hydraulic Fluid | Mineral oil HL, HLP per DIN 51524; HFC (water-glycol); HLPD, HVLP, HVLPD |
| Fluid Temperature Range | -30 °C to +80 °C (NBR seals) |
| Viscosity Range | 10-800 mm²/s |
| Weight (approx.) | 1.24 kg |
| Body Material | Steel / cast iron, zinc-plated |
No. A needle valve lets flow vary with ΔP. The 2FRM is pressure-compensated - the built-in compensator spool keeps the set flow essentially constant despite load or supply pressure changes (provided ≥~15 bar ΔP across compensator).
Loosen the lock ring / seal wire, turn the knurled knob clockwise to increase flow, counterclockwise to decrease. The knob has a relative scale - use a flow meter to correlate to actual L/min. After setting, tighten the lock ring / apply seal wire.
As a sandwich (stackable) valve between a directional control valve and the NG6 subplate (4× M5 bolts). Observe the arrow on the valve body - A→B = controlled/metered flow, B→A = free return.
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 use two 2FRM valves.
The pressure compensator typically needs min. ~15 bar differential pressure across the compensator to regulate properly. Supply pressure must exceed the highest load pressure + ~15-20 bar + line losses.
Both have identical flow characteristics and knob. B76 has a tamper-evident / sealable lock cap for appliions where the setting must not be altered after commissioning. B36 has a standard lock setscrew only.
NBR seals = mineral oil (HL/HLP) & HFC (water-glycol). For HEES/HETG biodegradable oils or HFD phosphate ester → specify FKM (Viton) seal variant.
