The Sun Hydraulics DPBPLAV (DPBPLAV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits, offering versatility in various hydraulic applications. This valve features an open pathway from port 1 to port 2, while port 3 remains blocked, making it suitable for use either independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold. Notably, blocking port 4 prevents the valve from shifting, while port 3 can serve as a work port. Both direct-acting and pilot-operated versions of this valve are interchangeable, sharing the same cavities and flow paths. The DPBPLAV supports a maximum operating pressure of up to 5000 psi (350 bar) and maintains a capacity of 7 gpm (28 L/min). It incorporates Sun\u2019s floating style construction to minimize internal part binding due to excessive installation torque or machining variations. The valve's design allows modulation between two positions rather than maintaining a bistable state. It is important to note that maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. Additional specifications include a cavity size of T-21A, with factory pressure settings established at a flow rate of 4 gpm (15 L/min). The control pilot flow ranges between 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with maximum valve leakage limited to 1 in\u00b3/min at pressures of up to 1000 psi (15 cc/min at 70 bar). The adjustment screw requires an internal hex size of \\(5/32\\) in. (4 mm), with torque specifications provided for both installation and locknut adjustments. This cartridge is ideal for applications requiring precise modulation and reliable performance under varying pressure conditions, ensuring efficient control 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.
