The Sun Hydraulics FREALAN (Material Number: FREALAN) is a versatile bypass-restrictive, fixed-orifice, priority flow control valve designed to manage input flow efficiently. It directs the input flow at port 1 to fulfill the priority flow requirement at port 3. Any excess input flow is diverted through port 2 and can be utilized in secondary circuits. This valve requires a customer-specified flow rating, with factory settings accurate within a 10% margin of the requested value. The maximum pressure at port 3 should not exceed 3000 psi (210 bar). A tunable adjustment control option allows for up to a 22% variation from the nominal factory preset flow, adjustable over three turns of the screw. Both priority and bypass flows are operable up to system pressure, maintaining consistent priority despite input variations. The design ensures that bypass flow only becomes available once priority needs are met, and pressure at port 2 can surpass that at port 3. With a sharp-edged orifice design, it minimizes variations due to viscosity changes and features Sun's floating style construction to reduce internal binding risk due to installation torque or machining variations. The valve fits into a T-17A cavity and belongs to Series 3 with 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). Installation requires specific torque settings for both the valve body and locknut. Additionally, it includes Viton seals for reliable performance under various conditions.

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.
