The Sun Hydraulics DPBNCAV (Material Number: DPBNCAV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It is versatile in application, capable of functioning independently or in conjunction with larger pilot-operated directional cartridges or logic cartridges. This valve shifts based on the pressure differential between port 1 and port 4, which must exceed the set threshold for activation. Port 4 can be blocked to maintain the valve's position, while port 3 serves as a work port with a maximum pressure limit of 3000 psi due to fatigue strength constraints. The valve's design incorporates Sun's floating style construction to minimize binding risks caused by installation torque or cavity machining variations. The DPBNCAV fits a T-21A cavity and belongs to Series 1, offering a capacity of 7 gpm (28 L/min). Factory settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure reaching up to 5000 psi (350 bar). The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), and the valve exhibits minimal leakage at maximum specified conditions. Adjustment of the pressure setting is achieved through clockwise turns, with specific torque requirements for installation and locknut adjustments provided for optimal performance. This model is not bistable but can modulate between two positions based on operational demands. For applications where pilot flow becomes significant beyond the valve setting, considering a direct-acting version may be beneficial. The DPBNCAV weighs approximately .60 lb (0.30 kg) and utilizes Viton seals for enhanced durability and performance reliability in various hydraulic systems.

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.
