The Sun Hydraulics DPBOKEN (Material Number: DPBOKEN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to activate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses a predetermined setting, providing flexibility in hydraulic circuit design. Port 4 can be blocked to prevent the valve from shifting, while port 3 serves as a work port. Notably, direct-acting and pilot-operated versions are interchangeable, sharing the same cavity and flow paths. The DPBOKEN incorporates Sun's floating style construction, reducing the risk of internal part binding due to excessive installation torque or machining variations. It has 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). The maximum pressure at port 3 should not exceed 3000 psi (210 bar), considering fatigue strength limits. This valve is not bistable but can modulate between two positions based on pilot pressure exceeding the valve setting. Pilot flow may become significant if this occurs; switching to a direct-acting version might resolve this issue. The valve features an adjustment screw with an internal hex size of 5/32 inch (4 mm) and requires installation torque between 30-35 lbf ft (41-47 Nm). It also includes a locknut with a hex size of 9/16 inch (15 mm) and torque specification of 80-90 lbf in (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for reliable performance under varied conditions.

Pilot-operated, 3-way directional cartridges (1 blocked, 2 to 3 open) 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.
