The Sun Hydraulics DPBNLJV (DPBNLJV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can operate independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds its preset value, and it features a unique design where port 4 can be blocked to prevent shifting, while port 3 serves as a work port. Notably, the direct-acting and pilot-operated versions are interchangeable, fitting the same cavities with identical flow paths. The DPBNLJV model is capable of modulating between two positions without being bistable. It has a maximum operating pressure of 5000 psi (350 bar) and a capacity of handling up to 7 gpm (28 L/min). The valve features Sun's floating style construction to minimize internal binding due to installation torque or machining variations. For optimal performance, the maximum pressure at port 3 should not exceed 3000 psi (210 bar), adhering to fatigue strength limits rather than hydraulic limits. Additional specifications include a control pilot flow range of 7-10 in\u00b3/min (0.11-0.16 L/min), and maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The adjustment mechanism allows for fine-tuning with up to five clockwise turns needed to increase settings, utilizing an internal hex size of 5/32 inches (4 mm). The valve's installation torque ranges from 30-35 lbf\u00b7ft (41-47 Nm), ensuring secure placement within systems requiring precise hydraulic control solutions.

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.
