The Sun Hydraulics DPBNKJV (DPBNKJV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can operate independently or in conjunction with larger pilot-operated directional cartridges or logic cartridges. It shifts when the pressure differential between port 1 and port 4 surpasses the set threshold. Port 4 can be blocked to prevent shifting, while port 3 serves as a work port. The valve is interchangeable with direct-acting versions, sharing the same cavities and flow paths. Pressure at port 4 is directly additive to the valve's setting, and it is capable of modulating between two positions rather than being bistable. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits, though this does not pertain to hydraulic operating limits. The DPBNKJV incorporates Sun's floating style construction, which minimizes internal binding risks due to excessive installation torque or machining variations in cavity/cartridge setups. It fits a T-21A cavity and belongs to Series 1 with a capacity of 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), and maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). The adjustment involves up to five clockwise turns to increase the setting, with specific torque requirements for installation and locknut adjustments. The model weighs approximately .60 lb (.30 kg), and a Viton seal kit is available for maintenance needs.

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.
