The Sun Hydraulics DPCNCDN (DPCNCDN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for use in moderate flow circuits. This versatile valve can function independently or be utilized to actuate larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the preset threshold. Notably, port 4 can be blocked to prevent the valve from shifting, and port 3 can serve as a work port. The direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities with identical flow paths. The DPCNCDN model incorporates Sun's floating style construction, which minimizes the risk of internal component binding due to excessive installation torque or machining variations in cavity/cartridge configurations. It features a cavity size of T-22A and belongs to series 2 with a capacity of 15 gpm (60 L/min). The maximum operating pressure for this valve is rated at 5000 psi (350 bar), while pressure at port 4 directly adds to the valve's setting. This model is not bistable; it can modulate between two positions depending on system requirements. It is recommended that maximum pressure at port 3 be limited to 3000 psi (210 bar) due to fatigue strength constraints rather than hydraulic operational limits. Control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), with maximum valve leakage at specified conditions being no more than 1 in\u00b3/min (1000 psi). The adjustment mechanism allows for fine-tuning with up to five clockwise turns required to increase the setting, facilitated by an internal hex size of 5/32 inch (4 mm) for the adjustment screw and a locknut hex size of 9/16 inch (15 mm).

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.
