The Sun Hydraulics DPBPLAN (Material Number: DPBPLAN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or in conjunction with larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses a predetermined setting, with the option to block port 4 to prevent shifting. Port 3 serves as a work port, and both direct-acting and pilot-operated versions of these valves are interchangeable, sharing the same cavities and flow paths. This model features a maximum operating pressure of 5000 psi (350 bar) and accommodates a capacity of up to 7 gpm (28 L/min). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), ensuring optimal performance. The valve's design incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations in the cavity/cartridge. Notably, this valve is not bistable; it can modulate between two positions as needed. It is essential to limit the maximum pressure at port 3 to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. For applications where pilot flow may become significant when exceeding the valve setting, considering the direct-acting version might be beneficial. Additional specifications include control pilot flow ranging from 7-10 in\u00b3/min (0.11-0.16 L/min), maximum valve leakage at 1 in\u00b3/min/1000 psi (15 cc/min/70 bar), and an adjustment range that increases with approximately five clockwise turns. The valve requires an installation torque between 30-35 lbf ft (41-47 Nm), with specific hex sizes for various components for ease of maintenance and adjustment.

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.
