The Sun Hydraulics FRDDOAV (FRDDOAV) is a bypass-restrictive, fixed-orifice, priority flow control valve designed to manage input flow efficiently across hydraulic systems. This valve directs the input flow at port 1 to satisfy the priority flow at port 3, with any excess bypassed out port 2 for use in secondary circuits. It features enhanced damping compared to the FRDA model to mitigate system instability issues effectively. Users must specify a flow rating, which the factory sets within a 10% margin of the requested setting. The valve can operate with maximum pressure at port 3 limited to 3000 psi (210 bar), and both priority and bypass flows are usable up to system operating pressure. Priority flow remains relatively stable despite variations in input flow, while bypass flow activates only after fulfilling priority requirements. Notably, pressure at the bypass port (port 2) can exceed that at the priority port (port 3). The sharp-edged orifice design minimizes variations due to viscosity changes. A tunable adjustment control offers up to a \u00b125% variation from the nominal preset flow, adjusted via three turns of an internal hex screw (5/32 in./4 mm). The Sun floating style construction reduces internal part binding risks due to installation torque or machining variations. Key specifications include a T-2A cavity, Series 2 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). Installation requires a valve hex size of 1-1/8 in. (28.6 mm) with torque between 45-50 lbf ft (61-68 Nm), and locknut torque between 80-90 lbf in. (9-10 Nm). The model weighs .40 lb (.20 kg) and uses Viton seal kits for cartridge applications.

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.
