The Sun Hydraulics DPCDKDN (DPCDKDN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses its setting, with the pressure at port 3 directly adding to the valve's setting. It is important to note that maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits, not hydraulic operating limits. This model features Sun's floating style construction, which helps reduce the risk of internal parts binding due to excessive installation torque or machining variations. The DPCDKDN fits into a T2A cavity and belongs to Series 2 with a capacity of up to 15 gpm (60 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), and it can handle a maximum operating pressure of up to 5000 psi (350 bar). Control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), while maximum valve leakage is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The adjustment for increasing settings requires up to five clockwise turns, with specific hex sizes for the valve, adjustment screw, and locknut provided for precise installation and maintenance. Additionally, this model weighs approximately .60 lb (0.30 kg) and utilizes Viton seals for reliable performance in hydraulic systems.

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 3 exceeds the setting.
- Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Port 3 can be blocked to prevent the valve from shifting.
- 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.
