The Sun Hydraulics DPCPCWN (DPCPCWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile device can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold, and it features the ability to block port 4 to prevent shifting. Port 3 serves as a work port, and both direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities with identical flow paths. The DPCPCWN is capable of modulating between two positions without being bistable, and it incorporates Sun's floating style construction to reduce the risk of internal binding due to excessive installation torque or machining variations. The valve's maximum operating pressure is rated at 5000 psi (350 bar), with a capacity of 15 gpm (60 L/min) and factory pressure settings established at 4 gpm (15 L/min). It's important to note that maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. For installation, the valve requires a torque setting between 45-50 lbf ft (61-68 Nm), with an adjustment screw internal hex size of 5/32 in. (4 mm). The locknut hex size is set at 9/16 in. (15 mm) with a locknut torque of 80-90 lbf in. (9-10 Nm). This model weighs .60 lb (.30 kg) and uses a Viton seal kit identified as part number 990022006. The DPCPCWN ensures reliable performance in hydraulic systems requiring precise control over moderate flow rates while maintaining robust construction for long-term 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.
