The Sun Hydraulics DPCPKDN (DPCPKDN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile 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 preset threshold, with the option to block port 4 to prevent shifting. Port 3 serves as a work port, and the valve's design allows for interchangeability with direct-acting versions, fitting the same cavities and maintaining identical flow paths. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. The valve is capable of modulating between two positions but is not bistable. The DPCPKDN incorporates Sun's floating style construction, minimizing internal part binding from excessive installation torque or cavity machining variations. It fits into a T-22A cavity and belongs to Series 2 with a capacity of 15 gpm (60 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). Control pilot flow ranges from 10-15 in\u00b3/min (0.16-0.25 L/min), and maximum valve leakage is limited to 1 in\u00b3/min at 110 SUS (24 cSt). Adjustment of the valve setting requires up to five clockwise turns, with specific torque requirements for installation and locknut adjustments ensuring secure operation. Additionally, it features Viton seals for durability under various conditions and weighs approximately .60 lb (0.30 kg).

Pilot-operated, 3-way directional cartridges (1 to 2 open, 3 blocked) 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.
