The Sun Hydraulics DPBNKBN (DPBNKBN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for use in moderate flow circuits. This versatile valve can function independently or serve to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds the set threshold. Importantly, port 4 can be blocked to prevent shifting, while port 3 serves as a work port with a maximum pressure limit of 3000 psi (210 bar) due to fatigue strength considerations. The valve is not bistable and can modulate between two positions. It features interchangeable direct-acting and pilot-operated versions that fit identical cavities and have the same flow paths. The DPBNKBN utilizes Sun's floating style construction to minimize internal binding risks from excessive installation torque or machining variations in cavity and cartridge design. With a capacity of 7 gpm (28 L/min) and factory pressure settings established at 4 gpm (15 L/min), this valve supports a maximum operating pressure of 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), with maximum valve leakage at 1 in\u00b3/min at 110 SUS (24 cSt). Adjustments are made via an internal hex screw with a locknut for secure settings, requiring specific torque values for installation. This model weighs approximately .60 lb (0.30 kg) and is compatible with Viton seal kits under part number 990021006. Its robust design ensures reliability across various applications where modulating pressure control is essential, offering fast response times and stability even under challenging conditions.

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.
