The Sun Hydraulics DPCNCAV (DPCNCAV) is a normally closed, pilot-operated, 2-way directional cartridge valve that offers versatility in moderate flow circuits. This valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds a specific setting. Notably, port 4 can be blocked to prevent the valve from shifting, and port 3 can serve as a work port with a maximum pressure limit of 3000 psi due to fatigue strength considerations. The valve is capable of modulating between two positions but is not bistable. The DPCNCAV model incorporates Sun's floating style construction, minimizing the risk of internal binding caused by excessive installation torque or machining variations in the cavity/cartridge. It fits T-22A cavities and offers a capacity of up to 15 gpm (60 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), and maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). For adjustments, the valve requires approximately five clockwise turns to increase its setting, and it features specific hex sizes for both the adjustment screw and locknut\u20145/32 in. (4 mm) for the adjustment screw and 9/16 in. (15 mm) for the locknut\u2014with corresponding torque specifications. The model weighs approximately .60 lb (.30 kg) and includes a Viton seal kit option for reliable performance under various 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.
