The Sun Hydraulics DPBPKAV (DPBPKAV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds a set threshold, with port 4 optionally blocked to prevent shifting. Port 3 serves as a work port, and both direct-acting and pilot-operated versions are interchangeable, fitting the same cavities and having identical flow paths. The valve is not bistable and can modulate between two positions. Key specifications include a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min). The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits. For optimal performance, factory pressure settings are established at a flow rate of 4 gpm (15 L/min). The valve features Sun's floating style construction to minimize internal part binding due to excessive installation torque or cavity/cartridge machining variations. Adjustments can be made with up to five clockwise turns to increase settings, using an internal hex size of 5/32 inches (4 mm) for the adjustment screw. The installation requires a torque of 30\u201335 lbf ft (41\u201347 Nm), with a locknut torque of 80\u201390 lbf in (9\u201310 Nm). Maximum valve leakage is specified at one in\u00b3/minute at 110 SUS (24 cSt). This model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for enhanced durability.

Pilot-operated, 3-way directional cartridges (1 to 2 open, 3 blocked) are switching devices typically used in moderate flow circuits. They can be used by themselves or to actuate larger pilot operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the setting.
- Port 4 can be blocked to prevent the valve from shifting.
- Port 3 can be used as a work port.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Pressure at port 4 is directly additive to the setting of the valve.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- When pilot pressure exceeds the valve setting, pilot flow may be a consideration. See performance curves for pilot consumption vs. load pressure above the valve setting. If this is a problem, the direct acting version of this valve would be a solution.
- 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.
