IFR10-39 Flow Fregulator Pressure-Compensated Valve

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.

Features of IFR10-39
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

Operation Symbol of IFR10-39
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.
