FR10-39 Flow Regulator, Pressure Compensated (FR10-39)
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 ➁) is blocked.
Product Operation
The FR10-39 maintains a constant flow rate from ➂ regardless of load pressure changes in the system downstream of ➂, or in the bypass leg at ➁. Reverse flow (➂ to ➀) bypasses 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, bypass pressure drop will increase unless a small
amount of leakage is provided for the priority port. Consult factory.
Product Features
• Bypass port ➁ may be fully pressurized.
• Fine low-torque adjustment.
• Hardened steel parts for long life.
• Quiet, modulated response.
• Industry common cavity.
