The Sun Hydraulics DPBPLDV (DPBPLDV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It functions by opening port 1 to port 2 while blocking port 3, and it can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve transitions when the pressure differential between port 1 and port 4 surpasses the preset value; however, blocking port 4 can prevent this shift. Port 3 serves as a work port, and both direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities with identical flow paths. The maximum operating pressure of the valve is set at 5000 psi (350 bar), while the maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limitations. The valve features a capacity of 7 gpm (28 L/min) and incorporates Sun's floating style construction to reduce internal part binding from excessive installation torque or machining variations. Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). It supports control pilot flow between 7-10 in\u00b3/min (0.11-0.16 L/min) and has a maximum valve leakage at specified conditions of up to 1 in\u00b3/min (15 cc/min). The adjustment requires up to five full clockwise turns to increase the setting, with specific hex sizes for various components ensuring precise installation and 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.
