The Sun Hydraulics FRDDOBN (FRDDOBN) is a bypass-restrictive, fixed-orifice, priority flow control valve designed to manage hydraulic flow efficiently. It takes input flow at port 1 and prioritizes it to port 3, with any excess being bypassed to port 2, which can be utilized in secondary circuits. This valve is highly damped compared to the FRDA model, addressing system instability issues effectively. Users must specify a flow rating, with factory settings accurate within 10% of the requested specification. The maximum pressure at port 3 should not exceed 3000 psi (210 bar), while both priority and bypass flows are usable up to the system's operating pressure. The valve maintains a relatively constant priority flow regardless of input variations, with bypass flow only available once priority requirements are met. Notably, pressure at the bypass port may exceed that at the priority port. The sharp-edged orifice design minimizes variations due to viscosity changes, and an adjustable control option allows for up to a 25% variation from the nominal preset flow using an internal adjustment screw. The Sun floating style construction minimizes risks of internal part binding due to excessive installation torque or machining variations. With a cavity size of T-2A and series number 2, this valve has a capacity of 12 gpm (45 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). It supports a maximum input flow of 30 gpm (120 L/min). The valve features specific dimensions for installation torque and adjustment screw sizes and weighs approximately .40 lb (.20 kg). A Viton seal kit is available for maintenance purposes.

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.
- This valve is more highly damped than the FRDA to help solve system instability problems.
- 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).
- 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.
- A tuneable adjustment control option provides up to +/- 25% variation from the nominal factory pre-set flow. Adjustment is done with +/- 3 turns of the adjust screw. Screw in (CW) to increase flow.
- 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.
