The Sun Hydraulics FRFALBV (FRFALBV) is a specialized bypass restrictive, fixed orifice, priority flow control valve designed to manage hydraulic flow efficiently. This valve directs input flow from port 1 to satisfy the priority flow at port 3, with any excess being bypassed through port 2 for potential use in secondary circuits. Users must specify a desired flow rating, which is factory set within 10% of the requested value. The maximum pressure at port 3 is advised not to exceed 3000 psi (210 bar). Notably, the valve includes a tunable adjustment option allowing up to a 22% variation from its nominal factory setting, adjustable via three turns of the screw. Both priority and bypass flows can operate up to system pressure levels, with priority flow remaining stable despite input variations. However, bypass flow only becomes available once the priority demand is met. The design features a sharp-edged orifice that minimizes fluctuations due to viscosity changes and incorporates Sun's floating style construction to prevent internal binding due to installation torque or machining variations. This model fits into cavity T19A and belongs to series 4 with a capacity of up to 50 gpm (200 L/min) and can handle maximum operating pressures of up to 5000 psi (350 bar). It supports input flows up to 120 gpm (480 L/min). The valve's hex size measures at 1-5/8 inches (41.3 mm), requiring an installation torque between 350-375 lbf ft (475-508 Nm). Additionally, it features an adjustment screw with an internal hex size of 5/32 inches (4 mm) and a locknut hex size of 9/16 inches (15 mm), torqued between 80-90 lbf in (9-10 Nm). The model weighs approximately 2.70 lb (1.25 kg) and uses Viton seals for optimal performance.

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.
- 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).
- A tuneable adjustment control option provides up to +/- 22% variation from the nominal factory pre-set flow. Adjustment is done with +/- 3 turns of the adjust screw. Screw in (CW) to increase flow.
- 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.
- 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.
