The Sun Hydraulics FRDDLBV (Material Number: FRDDLBV) is a bypass-restrictive, fixed-orifice, priority flow control valve designed to manage hydraulic flow efficiently. It directs input flow at port 1 to meet priority flow requirements at port 3, with any excess bypassed through port 2 for use in secondary circuits. This valve is highly damped compared to the FRDA model, addressing system instability issues. Users must specify a flow rating, with factory-set ratings accurate within 10% of the requested setting. The valve supports a maximum pressure of 3000 psi (210 bar) at port 3 and can handle both priority and bypass flows up to the system's operating pressure. Priority flow remains stable despite variations in input flow, while bypass flow activates only after fulfilling priority needs. The design allows for pressure at the bypass port (port 2) to exceed that at the priority port (port 3). It features a sharp-edged orifice to minimize viscosity-related flow variations and offers an adjustable control option for up to a 25% variation from the nominal preset flow via an adjustment screw with three turns. The Sun floating style construction reduces internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge settings. The valve fits into a T-2A cavity and belongs to Series 2 with a capacity of 12 gpm (45 L/min). It operates under pressures up to 5000 psi (350 bar) and accommodates maximum input flows of 30 gpm (120 L/min). Installation requires a torque of 45-50 lbf ft (61-68 Nm), with additional specifications including an adjustment screw internal hex size of 5/32 in. (4 mm) and locknut hex size of 9/16 in. (15 mm), requiring torque between 80-90 lbf in. (9-10 Nm). The model weighs .40 lb (.20 kg) and uses Viton seal kits for cartridge maintenance.

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.
