The Sun Hydraulics FVDALBV (FVDALBV) is a ventable, bypass-restrictive, fixed-orifice priority flow control valve designed to manage input flow effectively by directing it to satisfy priority flow at port 3. If the input surpasses the required priority flow, the surplus is diverted through port 2 for potential use in secondary circuits. The valve features a vent port (port 4) for remote control capabilities. Users must specify a factory-set flow rating, which is accurate within 10% of the requested setting. A pressure control at port 4 can limit pressure at the priority port (port 3), and if bypass port (port 2) pressure exceeds this setting, all flow will be redirected to the bypass port. The maximum pressure at port 3 should not exceed 3000 psi (210 bar), while both priority and bypass flows are operable up to system operating pressure levels. Priority remains stable despite variations in input flow, and bypass flow becomes available only after fulfilling priority requirements unless vented through port 4. The sharp-edged orifice design minimizes variations due to viscosity changes. An adjustable control option allows up to a \u00b125% variation from nominal factory preset flow using an adjustment screw with three turns for fine-tuning. The valve incorporates Sun's floating style construction to reduce internal part binding risks from excessive installation torque or cavity/cartridge machining variations. Key specifications include a T-22A cavity size, series 2 capacity of up to 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), and maximum input flow of 30 gpm (120 L/min). The valve's compact design includes a hex size of 1-1/8 inches (28.6 mm) and weighs approximately .40 lb (.20 kg).

Ventable, 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. A vent port (port 4) allows these valves to be controlled remotely.
- Customer must specify a flow rating. Factory set flow ratings are within +/- 10% of the requested setting.
- Using a pressure control on port 4 will limit the pressure at the priority port (port 3). If pressure on the bypass port (port 2) exceeds the setting of the pressure control, priority flow will be shut off and all the flow will go out the bypass port.
- 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, except when the valve is vented. When port 4 (vent) is open, all flow diverts to port 2 if pressure at port 1 (inlet) is 150 psi (10,5 bar) or higher.
- 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.
