The Sun Hydraulics DPCOLWV (DPCOLWV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It features one blocked port and an open flow path between ports 2 and 3, allowing it to function as a switching device. This valve can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the set threshold, with port 4 being blockable to prevent shifting. Port 3 serves as a work port, with maximum pressure limited to 3000 psi due to fatigue strength limits. Direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities and having identical flow paths. The pressure at port 4 directly adds to the valve's setting, allowing modulation between two positions rather than bistable operation. Pilot flow considerations arise when pilot pressure exceeds the valve setting; in such cases, opting for a direct-acting version may be beneficial. The DPCOLWV incorporates Sun's floating style construction, reducing the risk of internal parts binding from excessive installation torque or machining variations. The valve fits into a T22A cavity, has a capacity of 15 gpm (60 L/min), and operates at pressures up to 5000 psi (350 bar). It features adjustable settings with up to five clockwise turns for increased settings and minimal leakage at specified conditions. Installation requires specific torque values for both the valve body and locknut, ensuring secure placement in hydraulic systems.

Pilot-operated, 3-way directional cartridges (1 blocked, 2 to 3 open) 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.
