The Sun Hydraulics DPCNKWN (DPCNKWN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can be used independently or to actuate larger pilot-operated directional or logic cartridges. It functions by shifting when the pressure differential between port 1 and port 4 exceeds a preset threshold. The design allows port 4 to be blocked, preventing the valve from shifting, while port 3 can serve as a work port. Notably, direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities and sharing identical flow paths. The DPCNKWN is capable of modulating between two positions rather than being bistable, with a maximum pressure at port 3 limited to 3000 psi due to fatigue strength considerations. The valve's capacity is rated at 15 gpm (60 L/min), with factory pressure settings established at a flow of 4 gpm (15 L/min). It operates under a maximum pressure of 5000 psi (350 bar) and features control pilot flow ranging from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min). Maximum leakage at standard viscosity is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). This model incorporates Sun's floating style construction to minimize internal binding risks due to excessive installation torque or machining variations in cavity/cartridge setups. The DPCNKWN features an adjustment screw with an internal hex size of 5/32 inches (4 mm) and requires specific installation torques for both the valve and locknut components. This robust design ensures reliability and precision in hydraulic applications requiring modulation between two positions without bistability concerns.

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.
