A screw-in, cartridge-style, adjustable orifice, pressure-compensated, manually-operated, bypass-type hydraulic flow regulating valve. It can be used as a priority-type flow regulator or a restrictive-type 2-way flow regulator when the bypass port (port ②) is blocked.

| Input Flow | (Prority+Bypass): 0 to 38 lpm (0 to 10 gpm) nominal; 0 to 57 lpm (0 to 15 gpm) max. |
| Internal Leakage | 33ml/min. at 207 bar (3000 psi) |
| Adjustment Torque Required | Required torque 1.7 Nm at 207 bar (3000 psi) |
| Temperature | -40 to 100°C |
| Fluids | Mineral-based or synthetics with lubricating properties at viscosities of 7.4 to 420 cSt (50 to 2000 ssu) |
| Installation | No restrictions |
| Cavity | IVC10-3; See page 300 |
Material
| Cartridge | Weight: 0.30 kg. (0.68 lbs.); Steel with hardened work surfaces. Zinc-plated exposed surfaces; Seal: D type seal rings. |
| Standard Ported Body | Weight: 0.36 kg. (0.80 lbs.); Anodized high-strength 6061 T6 aluminum alloy, rated to 240 bar (3500 psi); Ductile iron and steel bodies available; dimensions may differ; Consult Inno. |
| 1. Bypass port ② may be fully pressurized. |
| 2. Fine low-torque adjustment. |
| 3. Hardened steel parts for long life. |
| 4. Quiet, modulated response. |
| 5. Industry common cavity |
The lFR10-39 maintains a constant flow rate from ③ regardless of load pressure changes in the system downstream of ③, or in the bypass leg at ②. Reverse flow(③ to ①) does not bypass the control orifice.The regulated flow increases from closed to fully open, with counter-clockwise rotation of the knob.
Note: When used as a bypass flow control in applications where the priority flow port will be blocked by external valving, the bypass pressure drop will increase unless a small amount of leakage is provided for the priority port.Consult Inno.
