The Sun Hydraulics DPBPLEV (DPBPLEV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component is used to either function 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 preset threshold, with the option to block port 4 to prevent shifting. Port 3 serves as a work port and should not exceed a maximum pressure of 3000 psi (210 bar) due to fatigue strength limits. The valve features interchangeable direct-acting and pilot-operated versions, sharing the same cavities and flow paths, which allows for flexibility in application. The DPBPLEV incorporates Sun's floating style construction, reducing the risk of internal binding caused by excessive installation torque or machining variations. It has a cavity type T-21A, series 1, with a capacity of 7 gpm (28 L/min), and factory pressure settings established at 4 gpm (15 L/min). Its maximum operating pressure is rated at 5000 psi (350 bar), with control pilot flow between 7 - 10 in\u00b3/min (0.11 - 0.16 L/min). Valve leakage at maximum is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The adjustment for increasing settings requires up to five clockwise turns, with specific torque requirements for installation and adjustment components: valve installation torque is set between 30 - 35 lbf ft (41 - 47 Nm), while locknut torque ranges from 80 - 90 lbf in (9 -10 Nm). The model weighs approximately .60 lb (.30 kg) and uses a Viton seal kit identified by part number: 990021006.

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.
