The Sun Hydraulics DPBPKWV (DPBPKWV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be utilized to actuate larger pilot-operated or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold, with port 4 capable of being blocked to prevent shifting. Port 3 serves as a work port and should not exceed a maximum pressure of 3000 psi (210 bar) due to fatigue strength limits. Despite this, the valve itself can handle a maximum operating pressure of up to 5000 psi (350 bar). The DPBPKWV is not bistable, offering modulation between two positions based on the pressure conditions. It incorporates Sun's floating style construction, minimizing internal binding risks from installation torque variations or cavity/cartridge machining discrepancies. The valve fits into cavity T-21A and boasts a capacity of 7 gpm (28 L/min), with factory pressure settings established at a flow rate of 4 gpm (15 L/min). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), while maximum valve leakage at standard viscosity is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). For adjustments, the screw requires a number of clockwise turns to increase setting up to five and a half times, with specific torque specifications for installation and locknut adjustments provided for optimal performance. The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for maintenance purposes.

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.
