The Sun Hydraulics FRDDLAV (FRDDLAV) is a highly efficient bypass-restrictive, fixed-orifice, priority flow control valve designed for hydraulic systems requiring precise flow management. This valve takes input flow at port 1 and prioritizes it to satisfy the flow requirements at port 3. Any excess flow is efficiently bypassed to port 2, which can be utilized in a secondary circuit. Notably, the FRDDLAV model is more highly damped than similar models to address system instability issues effectively. The valve requires customer-specified flow ratings, which are factory-set within a 10% margin of the requested setting. It operates with a maximum pressure of 3000 psi at port 3 and supports both priority and bypass flows up to the system's operating pressure. The design ensures that priority flow remains constant irrespective of input flow variations, while bypass flow becomes available only after fulfilling the priority requirements. A key feature is its sharp-edged orifice design that minimizes variations due to viscosity changes. Additionally, it offers a tunable adjustment control option allowing up to a 25% variation from the nominal factory preset flow via an adjustable screw mechanism. This model incorporates Sun's floating style construction to prevent internal binding caused by excessive installation torque or machining variations in cavity/cartridge setups. It fits into a T-2A cavity and belongs to Series 2 with a capacity of 12 gpm (45 L/min) and can handle a maximum input flow of 30 gpm (120 L/min). The valve's hex size is 1-1/8 inches (28.6 mm), with an installation torque range of 45-50 lbf ft (61-68 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), and the locknut requires a torque of 80-90 lbf in (9-10 Nm). This robust hydraulic component weighs approximately .40 lb (.20 kg) and includes Viton seal kits for reliable operation 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.
- 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.
