The Sun Hydraulics DPCMKDN (DPCMKDN) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It serves as a switching device and can be utilized independently or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold, with port 4 capable of being blocked to prevent shifting. Port 3 is available for use as a work port. The valve's design allows for interchangeability with direct-acting versions, fitting the same cavities and maintaining identical flow paths. The DPCMKDN incorporates Sun's floating style construction to minimize internal binding due to excessive torque or machining variations. With a cavity size of T22A and series number 2, it has a capacity of 15 gpm (60 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), with maximum valve leakage at 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustments are made via an internal hex screw, requiring up to five clockwise turns to increase settings. The DPCMKDN is not bistable but can modulate between two positions, with pressure at port 4 directly adding to the valve setting. While this model is robust and stable under various conditions, it\u2019s important that maximum pressure at port 3 does not exceed 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. For applications requiring different performance characteristics, direct-acting versions may be considered as alternatives.

Normally open, 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.
