The Sun Hydraulics DPBBOKV (DPBBOKV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the predefined setting, with pressure at port 3 being directly additive to the valve setting. Consequently, port 3 may not be suitable as a work port in certain circuit configurations, and a four-port version might be more appropriate if this is a concern. The direct-acting and pilot-operated versions of these valves are interchangeable due to their compatibility with the same cavities and flow paths. The DPBBOKV model is not bistable; it can modulate between two positions based on pilot pressure exceeding the valve's setting, where pilot flow becomes an important consideration. This valve features Sun's floating style construction to minimize internal part binding caused by excessive installation torque or cavity/cartridge machining variations. It fits into a T-11A cavity and belongs to Series 1 with a capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Additional technical specifications include control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), maximum valve leakage at specified conditions of 1 in\u00b3/min (15 cc/min), and an adjustment requiring up to five clockwise turns to increase settings. The installation requires specific torque values for both the valve and locknut components, ensuring optimal performance within hydraulic systems where precise modulation is crucial.

Normally closed, pilot-operated, 2-way directional cartridges 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 3 exceeds the setting.
- Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- 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.
