The Sun Hydraulics DPBPLJV (DPBPLJV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It functions by switching between open and blocked states based on the pressure differential between port 1 and port 4, which must exceed a specific setting to initiate the shift. The valve can be used independently or for actuating larger pilot-operated or logic cartridges. Port 3 serves as a work port, while blocking port 4 prevents shifting. These valves are interchangeable with direct-acting versions, sharing cavity compatibility and flow paths. The valve is capable of modulating between two positions rather than being bistable, and it incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. The DPBPLJV has a maximum operating pressure of 5000 psi (350 bar) and features a capacity of 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). It is important to limit the maximum pressure at port 3 to 3000 psi (210 bar) due to fatigue strength limitations. The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), while maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustments are made via an internal hex screw, with up to five clockwise turns required to increase the setting. The valve's installation torque ranges from 30-35 lbf\u00b7ft (41-47 Nm). This model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for maintenance.

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.
