The Sun Hydraulics DPBNKBV (DPBNKBV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to control larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds a preset level. For applications requiring the valve to remain in its initial position, port 4 can be blocked. Additionally, port 3 serves as a work port with a maximum pressure limit of 3000 psi (210 bar), dictated by fatigue strength considerations. The DPBNKBV valve is not bistable and is capable of modulating between two positions, making it suitable for applications requiring variable flow control. The valve incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. It fits into a T21A cavity and belongs to series 1 with a capacity of 7 gpm (28 L/min). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), and the maximum operating pressure is rated at 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with maximum valve leakage at 110 SUS (24 cSt) limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustment for increasing settings requires up to fifty-five clockwise turns, and the valve features specific dimensions for installation torque and hex sizes for adjustment screw and locknut. The DPBNKBV model weighs approximately .60 lb (.30 kg) and includes Viton seal kits as an option for enhanced durability in various hydraulic systems.

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 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.
