The Sun Hydraulics DPCOLWN (DPCOLWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses a predetermined setting, with port 4 capable of being blocked to prevent shifting. Port 3 serves as a work port, and the valve's direct-acting and pilot-operated versions are interchangeable, fitting the same cavities and maintaining identical flow paths. The maximum allowable pressure at port 3 is capped at 3000 psi (210 bar) due to fatigue strength limits. Incorporating Sun's floating style construction, this valve minimizes the risk of internal parts binding from excessive installation torque or cavity/cartridge machining variations. It features a capacity of up to 15 gpm (60 L/min) and operates with a maximum pressure of 5000 psi (350 bar). The control pilot flow ranges between 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), while the maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The adjustment for increasing the setting requires approximately five full clockwise turns, with specific torque requirements for installation and locknut adjustments. This product is not bistable; it can modulate between two positions based on pilot pressure relative to its setting. If excessive pilot flow becomes an issue when surpassing the valve setting, opting for a direct-acting version could be beneficial. With its robust design and reliable performance, this cartridge valve is suitable for various hydraulic applications requiring precise control and modulation capabilities.

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.
