The Sun Hydraulics DPBOKBV (Material Number: DPBOKBV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses a preset threshold, with port 4 being blockable to prevent shifting. Port 3 serves as a work port, and the design allows interchangeability between direct-acting and pilot-operated versions due to their shared cavity fit and flow paths. The maximum pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength limitations rather than hydraulic operating constraints. Incorporating Sun's floating style construction, this valve minimizes the risk of internal parts binding from excessive installation torque or machining variations. With a capacity of 7 gpm (28 L/min) and factory pressure settings established at 4 gpm (15 L/min), it can handle maximum operating pressures up to 5000 psi (350 bar). The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with maximum valve leakage at specified conditions being minimal at just 1 in\u00b3/min (15 cc/min). For setting adjustments, the valve requires up to five clockwise turns, and it features specific hex sizes for installation torque and adjustment screw operations. The DPBOKBV model weighs approximately .60 lb (0.30 kg) and includes a Viton seal kit for maintenance needs. This non-bistable valve modulates efficiently between two positions, offering reliable performance in various hydraulic applications where precise control is essential.

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.
