The Sun Hydraulics DPCNCWV (DPCNCWV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It can function independently or be used to actuate 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, with the option to block port 4 to prevent shifting. Port 3 is available for use as a work port, and both direct-acting and pilot-operated versions of this valve are interchangeable, fitting the same cavities and maintaining identical flow paths. The pressure at port 4 directly adds to the valve's setting, allowing modulation between two positions rather than bistable operation. This model incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. It features a T22A cavity with a series 2 capacity of up to 15 gpm (60 L/min) and is factory set at a flow rate of 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with control pilot flow ranging from 10-15 in\u00b3/min (0.16-0.25 L/min). Valve leakage at maximum conditions is limited to 1 in\u00b3/min (15 cc/min) at 1000 psi (70 bar). The DPCNCWV offers user-adjustable settings via an internal hex adjustment screw, requiring up to five turns clockwise for increased settings. Installation requires a torque range of 45-50 lbf\u00b7ft (61-68 Nm), while the locknut demands a torque of 80-90 lbf\u00b7in (9-10 Nm). This model weighs approximately .60 lb (.30 kg) and includes Viton seal kits for enhanced durability and performance under varying hydraulic conditions.

Normally closed, pilot-operated, 2-way directional cartridges 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.
