The Sun Hydraulics DPBNKAN (DPBNKAN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can act independently or be used to control larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds a predetermined setting, with the option to block port 4 to prevent movement. Port 3 serves as a work port and should not exceed a maximum pressure of 3000 psi (210 bar) due to fatigue strength limitations. Notably, this valve is not bistable; it can modulate between two positions based on system demands. The DPBNKAN model features Sun's floating style construction, reducing the risk of internal binding due to excessive installation torque or machining variations. It fits into cavity T-21A 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), and it can handle a maximum operating pressure of up to 5000 psi (350 bar). It provides control pilot flow rates between 7-10 in\u00b3/min (0.11-0.16 L/min) and maintains maximum valve leakage at just 1 in\u00b3/min at 110 SUS (24 cSt). The adjustment mechanism allows for up to five turns clockwise to increase the setting, with specific torque requirements for installation and locknut adjustments. This valve's design ensures reliable operation in various hydraulic applications where precise modulation between positions is essential. The use of Viton seals enhances durability under challenging conditions, making it suitable for demanding hydraulic systems requiring robust performance and minimal leakage.

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.
