The Sun Hydraulics FRDDLBN (FRDDLBN) is a bypass restrictive, fixed orifice, priority flow control valve designed to manage hydraulic flow efficiently. This valve takes input flow at port 1 and prioritizes the flow at port 3. If the input flow exceeds the priority requirement, the excess is bypassed through port 2, allowing for secondary circuit utilization. The FRDDLBN is engineered with enhanced damping compared to the FRDA model, addressing potential system instability issues. It requires specifying a factory-set flow rating with an accuracy of \u00b110% of the requested setting. Operating pressures for port 3 should not exceed 3000 psi (210 bar), while both priority and bypass flows can function up to system operating pressure levels. This model features a sharp-edged orifice design that minimizes variations due to viscosity changes and includes a tunable adjustment control option allowing up to a 25% variation from its nominal preset flow via three turns of an adjustment screw. The Sun floating style construction reduces internal part binding risks from excessive installation torque or machining variations within cavities or cartridges. Key specifications include a T2A cavity type, Series 2 designation, with a capacity of 12 gpm (45 L/min) and maximum operating pressure of 5000 psi (350 bar). The maximum input flow is rated at 30 gpm (120 L/min). Installation requires a valve hex size of 1-1/8 inches (28.6 mm) and torque between 45-50 lbf ft (61-68 Nm). Additionally, it uses an internal hex size adjustment screw of 5/32 inches (4 mm) and locknut hex size of 9/16 inches (15 mm), with locknut torque specifications between 80-90 lbf in (9-10 Nm). The model weight is approximately .40 lb (.20 kg), and it comes with a Viton seal kit cartridge option.

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.
