FR10-33 Valve

SYMBOL:
FR10-33 Valve symbol

DESCRIPTION
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 (2) is blocked.

OPERATION
The FR10-33 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) 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.

FEATURES
• Bypass port 2 may be fully pressurized.
• Fine low-torque adjustment.
• Hardened steel parts for long life.
• Quiet, modulated response.
• Industry-common cavity.
