The Sun Hydraulics FRDDOBV (FRDDOBV) is a bypass restrictive, fixed orifice, priority flow control valve designed to manage input flow at port 1 by satisfying priority flow requirements at port 3. Any excess input flow is redirected through port 2 and can be utilized in secondary circuits. This valve is engineered to address system instability issues with its highly damped design compared to the FRDA model. Users must specify a flow rating, which will be factory set within a 10% accuracy of the requested setting. The maximum pressure at port 3 should not exceed 3000 psi (210 bar), and both priority and bypass flows are operable up to the system's operating pressure. The priority flow remains constant despite input variations, while bypass flow becomes available only after priority requirements are met. Notably, the pressure at the bypass port may surpass that of the priority port. The valve features a sharp-edged orifice design that minimizes flow variations resulting from viscosity changes. It also offers an adjustable control option allowing up to a 25% variation from the nominal factory preset flow, adjustable via three turns of an internal hex screw. The Sun floating style construction minimizes binding risks due to excessive installation torque or machining variations. Key specifications include a T2A cavity series with a capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), and maximum input flow of 30 gpm (120 L/min). The valve's hex size measures 1-1/8 inches (28.6 mm) with an installation torque range between 45-50 lbf ft (61-68 Nm). Additional details include an adjustment screw internal hex size of 5/32 inches (4 mm), locknut hex size of 9/16 inches (15 mm), locknut torque range between 80-90 lbf in (9-10 Nm), and model weight of .40 lb (.20 kg).

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.
