The Sun Hydraulics DPBNCBV (DPBNCBV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can be utilized independently or to actuate larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold. Notably, port 4 can be blocked to prevent shifting, while port 3 serves as a work port with a maximum pressure limit of 3000 psi (210 bar) due to fatigue strength considerations. The valve is capable of modulating between two positions and incorporates Sun's floating style construction to minimize internal binding from installation torque or cavity machining variations. The DPBNCBV fits into the T-21A cavity and belongs to Series 1 with a capacity of handling up to 7 gallons per minute (28 liters per minute). Factory pressure settings are established at a flow rate of 4 gallons per minute (15 liters per minute), with the maximum operating pressure rated at 5000 psi (350 bar). The control pilot flow ranges from 7 to 10 cubic inches per minute (0.11 to 0.16 liters per minute), and maximum valve leakage at specific viscosity conditions is limited to 1 cubic inch per minute at 1000 psi (15 cc/min at 70 bar). Additional specifications include an adjustment capability of up to five clockwise turns for setting increases, with specific torque requirements for installation and adjustment components. The valve has a hex size of .78 inches (22.2 mm) for installation, requiring a torque between 30 and 35 lbf-ft (41-47 Nm), while the internal hex size for adjustment screws is .156 inches (4 mm). The locknut hex size measures .5625 inches (15 mm) with a torque range of 80-90 lbf-in (9-10 Nm). The model weighs approximately .60 pounds (.30 kg) and utilizes Viton seal kits for enhanced durability in various applications.

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.
