The Sun Hydraulics DPCPLDN (DPCPLDN) 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 cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds the preset value, with port 4 being blockable to prevent shifting and port 3 usable as a work port. The design allows for interchangeable use with direct-acting versions, fitting the same cavities and providing identical flow paths. This valve offers a maximum operating pressure of 5000 psi (350 bar) and a capacity of up to 15 gpm (60 L/min). It features Sun's floating style construction, minimizing internal binding risks due to installation torque or machining variations. The valve is not bistable; instead, it modulates between two positions based on pressure conditions. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength considerations. Additional specifications include a cavity size of T22A, series number 2, and factory pressure settings established at 4 gpm (15 L/min). Control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), with a maximum valve leakage at standard viscosity conditions of 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustment involves up to five clockwise turns to increase settings, with specific torque requirements for installation and adjustment components. The DPCPLDN model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for optimal performance. It is particularly suitable when precise modulation between open and closed states is required without bistability concerns.

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.
