FLOW CONTROLS
DESCRIPTION
A screw-in, cartridge-style, adjustable orifi ce, pressure-compensated, manually-
operated, bypass-type hydraulic fl ow regulating valve. It can be used as a priority-type
fl ow regulator or a restrictive-type 2-way fl ow regulator when the bypass port (port
➁)
is blocked.
OPERATION
The FR10-39 maintains a constant fl ow rate from ➂ regardless of load pressure
changes in the system downstream of
➂, or in the bypass leg at ➁. Reverse fl ow
(
➂ to ➀) bypasses the control orifi ce.
The regulated fl ow increases from closed to fully open, with counter-clockwise
rotation of the knob.
Note: When used as a bypass fl ow control in applications where the priority fl ow 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.
FEATURES
• Bypass port ➁ may be fully pressurized.
• Fine low-torque adjustment.
• Hardened steel parts for long life.
• Quiet, modulated response.
• Industry common cavity.
