The Sun Hydraulics DPCPKWV (DPCPKWV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It features a configuration where ports 1 and 2 are open, and port 3 is blocked, allowing it to function either independently or to control larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds a predetermined setting. Notably, port 4 can be blocked to prevent shifting, while port 3 serves as a work port with a maximum pressure limit of 3000 psi due to fatigue strength considerations. This valve is not bistable, meaning it can modulate between two positions rather than just switching on or off. It incorporates Sun's floating style construction to reduce the risk of internal binding caused by excessive installation torque or machining variations. The DPCPKWV fits into cavity T22A, belongs to series 2, and has a capacity of handling flow rates up to 15 gpm (60 L/min). It operates at a maximum pressure of 5000 psi (350 bar) and has specific control pilot flow requirements ranging from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min). The adjustment mechanism allows for setting changes with up to five clockwise turns, while the valve's installation requires specific torque settings: valve installation torque ranges from 45-50 lbf.ft (61-68 Nm), and locknut torque ranges from 80-90 lbf.in (9-10 Nm). The valve weighs approximately .60 lb (0.30 kg) and utilizes Viton seal kits for effective sealing performance. This versatile cartridge is suitable for applications requiring reliable modulation between positions without bistability concerns.

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.
