The Sun Hydraulics DPBBCWN (DPBBCWN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 exceeds a predefined setting, with pressure at port 3 being directly additive to the setting. Notably, this means port 3 may not be suitable as a work port in certain circuits, in which case a four-port version might be preferable. The DPBBCWN offers interchangeability between direct-acting and pilot-operated versions, as they share cavity compatibility and flow paths. While not bistable, this valve can modulate between two positions based on pilot pressure relative to its setting. If pilot flow becomes an issue when the pressure exceeds the valve setting, switching to a direct-acting version could resolve it. The valve incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. Key specifications include a T-11A cavity type, Series 1 classification, and a capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 - 0.16 L/min), and maximum valve leakage is rated at 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The adjustment screw requires up to five clockwise turns for increased settings and features an internal hex size of 5/32 inches (4 mm). Installation torque is specified at 30 - 35 lbf\u00b7ft (41 - 47 Nm), while locknut torque is set at 80 - 90 lbf\u00b7in (9 -10 Nm). The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for optimal 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.
