The Sun Hydraulics DPCNKDV (DPCNKDV) 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 or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds a preset value, with the option to block port 4 to prevent shifting. Port 3 is available as a work port and should not exceed a maximum pressure of 3000 psi (210 bar) due to fatigue strength limits. The valve's design allows for modulation between two positions rather than being bistable. This model incorporates Sun's floating style construction, which minimizes internal binding risks caused by excessive installation torque or cavity machining variations. It fits the T-22A cavity and belongs to Series 2, with a capacity of handling up to 15 gpm (60 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure capability of up to 5000 psi (350 bar). The control pilot flow ranges from 10-15 in\u00b3/min (0.16-0.25 L/min), and it has minimal leakage rates under specified conditions. The valve features an adjustment mechanism that requires approximately five clockwise turns to increase the setting, with specific hex sizes for installation and adjustment components: the valve hex size is 1-1/8 inches (28.6 mm), while the locknut hex size is 9/16 inches (15 mm). The model weighs approximately .60 lb (0.30 kg) and includes a Viton seal kit option identified as part number 990022006 for maintenance needs.

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.
