The Sun Hydraulics DPBPCWN (DPBPCWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It is particularly effective in applications where switching devices are required to control flow from port 1 to port 2 while keeping port 3 blocked. This valve can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds a pre-set threshold. Port 4 can be blocked to prevent shifting, and port 3 serves as a work port with a maximum pressure limit of 3000 psi due to fatigue strength considerations. The DPBPCWN features interchangeable direct-acting and pilot-operated versions that fit the same cavities and share identical flow paths. This model incorporates Sun's floating style construction, which minimizes the potential for internal binding due to excessive installation torque or machining variations in the cavity/cartridge interface. The valve has a capacity of 7 gpm (28 L/min) and can handle a maximum operating pressure of up to 5000 psi (350 bar). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). Adjustment parameters include up to five clockwise turns to increase settings, with a valve hex size of .78 inches (22.2 mm) and an installation torque range of 30-35 lbf\u00b7ft (41-47 Nm). The adjustment screw uses an internal hex size of .532 inches (4 mm), while the locknut hex size is .916 inches (15 mm), requiring a locknut torque between 80-90 lbf\u00b7in. The model weighs approximately .60 lbs (.30 kg) and uses Viton seal kits 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.
