The Sun Hydraulics DPBPCJV (DPBPCJV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits, offering versatility in hydraulic systems. This valve is particularly effective in applications where it can independently function 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 predetermined setting, with an option to block port 4 to prevent shifting. Port 3 serves as a work port, and the valve's design allows for interchangeability between direct-acting and pilot-operated versions, fitting the same cavities and maintaining consistent flow paths. The DPBPCJV model incorporates Sun's floating style construction, which minimizes internal part binding due to installation torque or machining variations. It features a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). This valve is not bistable; instead, it modulates between two positions based on system demands. It's crucial to limit maximum pressure at port 3 to 3000 psi (210 bar) due to fatigue strength limits. Additional specifications include a control pilot flow of 7-10 in\u00b3/min (0.11-0.16 L/min), maximum valve leakage of 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar), and an adjustment range that requires up to five full clockwise turns to increase the setting. The DPBPCJV's installation involves specific torque requirements for both the valve itself and its locknut components, ensuring secure placement within 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 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.
