The Sun Hydraulics DPBBCKN (DPBBCKN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It operates by shifting when the pressure differential between port 1 and port 3 exceeds a specified setting, making it suitable for use either independently or to actuate larger pilot-operated directional or logic cartridges. This valve features a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 7 gpm (28 L/min). Notably, the pressure at port 3 directly adds to the valve's setting, which may limit its use as a work port in certain circuits; in such cases, a four-port version might be preferable. The DPBBCKN is not bistable and can modulate between two positions. It incorporates Sun's floating style construction to minimize internal binding issues due to excessive installation torque or cavity-cartridge machining variations. The valve fits into T11A cavities and is interchangeable with direct-acting versions, which share the same flow paths and cavity dimensions. For those concerned about pilot flow consumption when pilot pressure exceeds the valve setting, this can be addressed by opting for the direct-acting variant. The valve includes an adjustment feature that allows up to 5.5 clockwise turns to increase its setting, with specific torque requirements for installation and adjustment components. The maximum leakage rate at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar), ensuring efficient operation with minimal fluid loss. The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits (990011006) for effective sealing performance under various 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 3 exceeds the setting.
- Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- 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.
