The Sun Hydraulics FVFALBN (FVFALBN) is a ventable, bypass-restrictive, fixed-orifice priority flow control valve designed to manage input flow efficiently across multiple ports. It takes an input flow at port 1 and prioritizes the flow to port 3. Any excess flow beyond the priority requirement is bypassed through port 2, which can be utilized in secondary circuits. The valve features a vent port at port 4, allowing for remote control. The factory sets the flow ratings within a 10% margin of the requested setting, and users can adjust the flow by up to 25% using an adjustment screw with three turns for fine-tuning. The valve's sharp-edged orifice design minimizes variations due to changes in fluid viscosity, ensuring consistent performance. It incorporates Sun's floating style construction to prevent internal parts from binding due to excessive installation torque or machining variations. The FVFALBN has a maximum operating pressure of 5000 psi (350 bar) and can handle a capacity of up to 50 gpm (200 L/min). The maximum input flow it can manage is 120 gpm (480 L/min), with both priority and bypass flows usable up to system operating pressure. The valve's design ensures that priority remains relatively constant regardless of input flow variations. Bypass flows are available only after meeting priority requirements unless the valve is vented; when open, all flows divert to port 2 if inlet pressure at port 1 exceeds 150 psi (10.5 bar). This product is ideal for applications requiring precise control over hydraulic circuits where maintaining consistent priority flow is crucial while utilizing excess capacity effectively in secondary circuits.

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.
