The Sun Hydraulics FREALBV (Material Number: FREALBV) is a bypass-restrictive, fixed-orifice, priority flow control valve designed to manage hydraulic flow efficiently. This valve takes an input flow at port 1 and prioritizes the flow to port 3. If the input surpasses the priority requirement, the excess is redirected to port 2, which can be utilized in secondary circuits. Customers must specify a desired flow rating, with factory-set ratings within 10% of the requested setting. The maximum pressure at port 3 should not exceed 3000 psi (210 bar), and both priority and bypass flows are functional up to system operating pressures. The valve features a tunable adjustment control option offering up to a 22% variation from its nominal factory preset flow, adjustable via three turns of an internal hex screw. A sharp-edged orifice design minimizes flow variations due to changes in viscosity. The valve incorporates Sun's floating style construction to reduce potential binding of internal parts during installation or machining variations. Key specifications include a T-17A cavity, Series 3 classification, and a capacity of up to 25 gpm (95 L/min). It can handle a maximum operating pressure of 5000 psi (350 bar) and an input flow of up to 60 gpm (240 L/min). The valve's hex size is 1-1/4 inches (31.8 mm) with an installation torque range of 150-160 lbf-ft (203-217 Nm). It also includes an adjustment screw internal hex size of 5/32 inches (4 mm) and a locknut torque range of 80-90 lbf-in (9-10 Nm). The model weighs approximately 1.25 lbs (0.60 kg) and comes with a Viton seal kit for cartridge applications.

Bypass/restrictive, fixed-orifice, priority flow controls take an input flow at port 1 and use it to satisfy the priority flow at port 3. If the input flow exceeds the priority flow requirement, the excess is bypassed out port 2. The bypass flow may be used in a secondary circuit.
- Customer must specify a flow rating. Factory set flow ratings are within +/- 10% of the requested setting.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar).
- A tuneable adjustment control option provides up to +/- 22% variation from the nominal factory pre-set flow. Adjustment is done with +/- 3 turns of the adjust screw. Screw in (CW) to increase flow.
- Both priority and bypass flow are usable up to the system operating pressure.
- Priority remains relatively constant regardless of variation in input flow.
- Bypass flow is not available until priority flow requirements are satisfied.
- Pressure at the bypass port (port 2) may exceed pressure at the priority port (port 3).
- The sharp-edged orifice design minimizes flow variations due to viscosity changes.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
