The Sun Hydraulics DPBNCWN (DPBNCWN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It serves as a versatile switching device that can function independently or be used to actuate 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 set threshold. Notably, port 4 can be blocked to prevent shifting, while port 3 may serve as a work port. The valve's design allows for interchangeability with direct-acting versions, fitting the same cavities and maintaining identical flow paths. This model incorporates Sun's floating style construction, which minimizes the risk of internal binding caused by excessive installation torque or variations in cavity/cartridge machining. The DPBNCWN has a capacity of 7 gpm (28 L/min) and operates at a maximum pressure of 5000 psi (350 bar). It features an adjustment mechanism allowing up to 5.5 clockwise turns to increase the setting, with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). The valve installation requires a torque of 30-35 lbf-ft (41-47 Nm), and it includes specific hex sizes for both the adjustment screw and locknut. This cartridge valve is not bistable; it modulates between two positions based on pressure conditions. Maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limitations rather than hydraulic operating limits. With its robust design and precise functionality, the Sun Hydraulics DPBNCWN is ideal for applications requiring reliable pressure modulation and control within specified operating parameters.

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.
