The Sun Hydraulics DPCPCBN (DPCPCBN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or in conjunction with larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds a specific setting, with the capability to block port 4 to prevent shifting. Port 3 serves as a work port, and both direct-acting and pilot-operated versions of these valves are interchangeable, sharing the same cavities and flow paths. The valve is not bistable but can modulate between two positions, with maximum pressure at port 3 limited to 3000 psi due to fatigue strength limits. The DPCPCBN incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations. It has a cavity size of T22A, series 2, with a capacity of 15 gpm (60 L/min) and factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with control pilot flow ranging from 10-15 in\u00b3/min (0.16-0.25 L/min). Valve leakage is minimal at maximum conditions, and adjustments are made via an internal hex screw. The valve installation requires specific torque values: valve hex size is 1-1/8 inches (28.6 mm), installation torque ranges from 45-50 lbf\u00b7ft (61-68 Nm), adjustment screw internal hex size is 5/32 inches (4 mm), locknut hex size is 9/16 inches (15 mm), and locknut torque ranges from 80-90 lbf\u00b7in (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and uses a Viton seal kit for maintenance.

Pilot-operated, 3-way directional cartridges (1 to 2 open, 3 blocked) 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 4 exceeds the setting.
- Port 4 can be blocked to prevent the valve from shifting.
- Port 3 can be used as a work port.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Pressure at port 4 is directly additive to the setting of the valve.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- 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.
