The Sun Hydraulics DPBNCJV (DPBNCJV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can be utilized independently or 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 preset threshold. Additionally, port 4 can be blocked to prevent shifting, while port 3 serves as a work port. The DPBNCJV valve is interchangeable with direct-acting versions, sharing identical cavities and flow paths. Notably, pressure at port 4 directly adds to the valve's setting, allowing modulation between two positions rather than bistable operation. The maximum pressure at port 3 is capped at 3000 psi (210 bar) due to fatigue strength considerations rather than hydraulic limits. When pilot pressure exceeds the valve setting, pilot flow becomes a factor; if problematic, opting for a direct-acting version may resolve this issue. The valve features Sun's floating style construction to minimize internal binding risks from excessive installation torque or cavity/cartridge machining variations. This model fits into cavity T-21A and boasts a capacity of 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). It supports a maximum operating pressure of up to 5000 psi (350 bar) and handles control pilot flows between 7-10 in\u00b3/min (0.11-0.16 L/min). The maximum allowable leakage at viscosity levels of 110 SUS (24 cSt) is limited to 1 in\u00b3/min per 1000 psi (15 cc/min per 70 bar). For adjustments, it requires up to five clockwise turns to increase settings, with specific torque requirements for installation and adjustment components provided for optimal performance.

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.
