The Sun Hydraulics FDFAKAV (FDFAKAV) is a fully adjustable, pressure-compensated flow control cartridge designed for precise flow regulation in both meter-in and meter-out applications. It is particularly effective in scenarios where there are wide pressure fluctuations. The device allows for infinite adjustment from nearly closed to maximum flow, thanks to its balanced adjustment mechanism which ensures ease of use even at high pressures. The integral high-capacity check valve facilitates unrestricted flow from port 2 to port 1, enhancing its functional versatility. This model features a sharp-edged orifice design that minimizes flow variations due to viscosity changes, ensuring consistent performance across different conditions. With a capacity of 50 gpm (200 L/min) and a maximum operating pressure of 5000 psi (350 bar), the FDFAKAV is robust and reliable for demanding hydraulic systems. It fits into cavity T18A and belongs to series 4, making it interchangeable with other 2-port flow control cartridges that share the same cavity size. The valve hex size is 1-5/8 inches (41.3 mm), with an installation torque requirement of 350-375 lbf-ft (475-508 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), while the locknut hex size is 9/16 inches (15 mm), requiring a torque of 80-90 lbf-in (9-10 Nm). The unit weighs approximately 3.30 lb (1.50 kg) and comes with Viton seal kits for compatibility with various fluid types; however, cartridges with EPDM seals should be used specifically in systems containing phosphate ester fluids to avoid seal damage from petroleum-based substances. Minimum leakage when shut off is .2 gpm (0.8 L/min), ensuring efficient operation without significant loss of fluid control.

Fully adjustable, pressure-compensated flow controls with reverse-flow check provide precise flow regulation for meter-in or meter-out applications where there may be wide pressure fluctuations. They are infinitely adjustable from nearly closed up to the maximum flow. An integral high-capacity check valve provides unrestricted flow from port 2 to port 1.
- All 2-port flow control cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). However, cartridge extension dimensions from the mounting surface may vary.
- A balanced adjustment mechanism allows for easy adjustment even at high pressures.
- The sharp-edged orifice design minimizes flow variations due to viscosity changes.
- Minimum leakage is .2 gpm (0,8 L/min) when the adjustment mechanism is turned to the shut-off position.
- Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
