The Sun Hydraulics DPBPKWN (DPBPKWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device, opening from port 1 to port 2 while blocking port 3, making it versatile for various hydraulic applications. This valve can operate independently or actuate larger pilot-operated or logic cartridges. Notably, the valve shifts when the pressure differential between port 1 and port 4 surpasses a preset threshold. Port 4 can be blocked to prevent shifting, and port 3 serves as a work port with a maximum pressure limit of 3000 psi (210 bar) due to fatigue strength considerations. The DPBPKWN model features interchangeable direct-acting and pilot-operated versions that fit identical cavities and maintain consistent flow paths. The valve is capable of modulating between two positions but is not bistable. It incorporates Sun's floating style construction to minimize internal binding risks due to excessive installation torque or cavity/cartridge machining variations. With a cavity size of T-21A and series number 1, this valve has a capacity of 7 gpm (28 L/min) with factory pressure settings established at 4 gpm (15 L/min). It operates at a maximum pressure of 5000 psi (350 bar) with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). The maximum valve leakage at viscosity levels of 110 SUS (24 cSt) is limited to 1 in\u00b3/min (15 cc/min) at pressures up to 1000 psi (70 bar). Adjustments are made via an internal hex screw requiring up to five clockwise turns, with specific torque requirements for installation and locknut adjustments ensuring secure fitting. The 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.
