The Sun Hydraulics DPBNCWV (DPBNCWV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It serves as a switching device that 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 4 surpasses the pre-set threshold. Notably, port 4 can be blocked to prevent any shift in the valve, while port 3 is available for use as a work port. Direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities and having identical flow paths. The DPBNCWV model is capable of modulating between two positions but is not bistable. It has a cavity size of T-21A, belongs to series 1, and offers a capacity of 7 gpm (28 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). The control pilot flow ranges between 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), and the maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). The valve features Sun\u2019s floating style construction, which minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. Adjustments can be made by turning clockwise up to five turns to increase settings. The installation requires specific torques: valve installation torque is between 30-35 lbf ft (41-47 Nm), adjustment screw internal hex size is ^5\u204432 in. (4 mm), locknut hex size is ^9\u204416 in. (15 mm), and locknut torque ranges from 80-90 lbf in. (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and includes a Viton seal kit under part number 990021006 for maintenance purposes.

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.
