The Sun Hydraulics DPBNKAV (DPBNKAV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It is versatile and can be used 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 set threshold. Port 4 can be blocked to prevent shifting, while port 3 serves 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 pressure at port 4 directly adds to the valve's setting, allowing modulation between two positions without being bistable. This model incorporates Sun's floating style construction, minimizing internal binding risks due to installation torque or machining variations. It features a T21A cavity with a series 1 capacity of 7 gpm (28 L/min) and factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure reaches up to 5000 psi (350 bar), with control pilot flow ranging from 7-10 in\u00b3/min (0.11-0.16 L/min). Valve leakage is minimal at a maximum of 1 in\u00b3/min (15 cc/min) under specific conditions. The DPBNKAV's adjustment mechanism requires up to five clockwise turns to increase the setting, with specific torque requirements for installation and locknut adjustments. It weighs approximately .60 lb (0.30 kg) and uses Viton seal kits for durability. This valve is particularly useful in applications requiring modulation between positions rather than bistability and offers a robust solution for moderate flow circuit needs while maintaining compatibility across different configurations within its operational limits.

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.
