The Sun Hydraulics DPBBKKN (DPBBKKN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for use in moderate flow hydraulic circuits. This versatile component can function independently or be employed to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses a predetermined setting, with pressure at port 3 directly adding to this setting. Therefore, port 3 may not be suitable as a work port in some circuit configurations, and a four-port version might be necessary if this is a concern. Both direct-acting and pilot-operated versions of these valves are interchangeable, sharing the same cavity and flow paths. Notably, the DPBBKKN is capable of modulating between two positions rather than being bistable. Key specifications include a T-11A cavity size, Series 1 classification, and a capacity of up to 7 gpm (28 L/min). It has a maximum operating pressure of 5000 psi (350 bar) and allows control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). Valve leakage at maximum is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The valve features an adjustment mechanism allowing up to five clockwise turns to increase the setting, with an installation torque requirement of 30-35 lbf ft (41-47 Nm). Additionally, it incorporates Sun's floating style construction which minimizes internal binding due to excessive installation torque or variations in cavity/cartridge machining. The product weighs approximately .60 lb (0.30 kg) and uses Viton seals for enhanced durability and performance.

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.
