The Sun Hydraulics FRFAXBN (Material Number: FRFAXBN) is a bypass-restrictive, fixed-orifice priority flow control valve designed to manage hydraulic flow efficiently. This component takes an input flow at port 1 and prioritizes the output at port 3, diverting any excess to port 2 for secondary circuit use. Users must specify a factory-set flow rating, which remains consistent within a 10% range of the requested setting. The valve can handle a maximum pressure of 3000 psi at port 3 and features a tuneable adjustment control option that allows for up to a 22% variation from the factory preset flow, adjusted via three turns of the screw. Both priority and bypass flows operate effectively up to system pressure levels, with priority remaining stable despite input fluctuations. Notably, the bypass flow only activates once priority needs are met, and pressure at port 2 can exceed that at port 3. Constructed with Sun's floating style design, this valve minimizes internal binding risks due to excessive torque or machining variations. It fits into cavity T19A and belongs to series 4 with a capacity of up to 50 gpm (200 L/min) and can withstand a maximum input flow of 120 gpm (480 L/min). The valve's hex size is 1-5/8 inches (41.3 mm), requiring an installation torque between 350-375 lbf ft (475-508 Nm). The adjustment screw uses an internal hex size of 5/32 inches (4 mm), while the locknut has a hex size of 9/16 inches (15 mm) with a torque requirement of 80-90 lbf in (9-10 Nm). This model weighs approximately 2.70 lb (1.25 kg) and supports Viton seal kits under part number 990019006 for reliable sealing performance.

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.
