The Sun Hydraulics FRFALBN (FRFALBN) is a bypass-restrictive, fixed-orifice, priority flow control valve designed to manage input flow efficiently. It takes an input flow at port 1 and directs it to satisfy the priority flow at port 3. Any excess input flow beyond the priority requirement is bypassed out of port 2, which can be utilized in a secondary circuit. The product requires the customer to specify a flow rating, with factory-set ratings accurate within 10% of the requested setting. The valve features a tuneable adjustment control option allowing up to 22% variation from the nominal factory preset flow through three turns of an adjust screw; turning clockwise increases the flow rate. Both priority and bypass flows are operable up to the system's maximum operating pressure of 5000 psi (350 bar). The sharp-edged orifice design minimizes variations due to viscosity changes, ensuring consistent performance. The FRFALBN model incorporates Sun's floating style construction, reducing the risk of internal parts binding due to excessive installation torque or machining variations. It fits into a T-19A cavity and belongs to series 4 with a capacity of up to 50 gpm (200 L/min) and can handle 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 and 375 lbf-ft (475-508 Nm). Additional specifications include an adjustment screw internal hex size of 5/32 inches (4 mm), locknut hex size of 9/16 inches (15 mm), and locknut torque between 80 and 90 lbf-in (9-10 Nm). The model weighs approximately 2.70 lb (1.25 kg) and utilizes Viton seal kits 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.
