The Sun Hydraulics DPBCKKN (DPBCKKN) is a pilot-operated, 3-way directional cartridge valve designed for use in moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the set threshold, with pressure at port 3 directly adding to the valve's setting. It is important to note that port 3 may not be suitable as a work port in certain circuits, though a four-port version of this valve could address such concerns. The DPBCKKN model is interchangeable with direct-acting versions, sharing cavity dimensions and flow paths. Key features include its ability to modulate between two positions rather than being bistable, and it incorporates Sun's floating style construction to reduce risks of internal binding from installation torque or machining variations. With a cavity size of T-11A and series designation of 1, the valve has a capacity of 7 gpm (28 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), while control pilot flow ranges from 7-10 in\u00b3/min (0.11-0.16 L/min). The maximum allowable leakage is specified at 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Installation specifics include a hex size of .78 inches (22.2 mm) for the valve body, torque requirements between 30-35 lbf ft (41-47 Nm), and adjustment screw internal hex size of .156 inches (4 mm). A locknut hex size of .5625 inches (15 mm) requires torque settings between 80-90 lbf in (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for maintenance.

Pilot-operated, 3-way directional cartridges (1 blocked, 2 to 3 open) 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.
- Port 3 can be blocked to prevent the valve from shifting.
- 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.
