The Sun Hydraulics DPBBKDN (DPBBKDN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses its set threshold. Notably, pressure at port 3 directly adds to the valve setting, which may limit its use as a work port in certain circuits; in such cases, a 4-port version might be more suitable. The DPBBKDN is not bistable and can modulate between two positions. With interchangeable direct-acting and pilot-operated versions that fit identical cavities and share flow paths, this valve offers flexibility in application. It incorporates Sun's floating-style construction to minimize internal part binding due to excessive installation torque or machining variations. The DPBBKDN fits into a T-11A cavity with a capacity of 7 gpm (28 L/min) and has a maximum operating pressure of 5000 psi (350 bar). Factory pressure settings are established at 4 gpm (15 L/min), with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). The valve features an adjustment screw with an internal hex size of 5/32 inch (4 mm) and requires specific installation torques: the valve itself needs between 30 to 35 lbf ft (41 to 47 Nm), while the locknut demands between 80 to 90 lbf in (9 to 10 Nm). Weighing approximately .60 lb (.30 kg), the DPBBKDN also allows for adjustments via clockwise turns to increase settings up to five times. Seal kits are available in Viton material under part number 990011006 for maintenance purposes.

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.
