FLOW CONTROLS
FR10-30A Regulator, Pressure-Compensated
DESCRIPTION
A screw-in, cartridge-style, fi xed orifi ce, pressure-compensated, bypass-type
hydraulic fl ow regulating valve, with limited range adjustment from a pre-determined
nominal setting.
OPERATION
The FR10-30A 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.
The valve will pressure-compensate once a minimum pressure drop (determined
by spring adjustment setting) is achieved from
➀ to ➂. This value will range from
approximately 4.8 to 13.8 bar (70 to 200 psid).
The cartridge may be adjusted to ±25% of nominal setting. At nominal setting,
pressure drop is approximately 9 bar (130 psid).
Flow out of priority port
➂ may vary based on input fl ow amount, particularly with
lower temperatures and increased fl uid viscosities. Settings may need to be
established through correlation study. Consult factory.
FEATURES
• Bypass port ➁ may be fully pressurized.
• Hardened steel parts for long life.
• Quiet, modulated response.
• Industry common cavity.
RATINGS
Operating Pressure: 207 bar (3000 psi)
Customer-Specifi ed Standard Flow Setting:
Low Range: 1.9 to 9.5 lpm (0.5 to 2.5 gpm);
Specify in 1.9 lpm (0.5 gpm) increments.

NOTE: For certain applications with substantial dynamic load changes, particularly in
cases where there is high differential pressure, we recommend the use of the
FR10-33 (page 5.372.1) or the FR10-39 (page 5.382.1) in place of this valve.
