The Sun Hydraulics DPBOCEN (DPBOCEN) is a versatile pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This valve features one blocked port and an open connection between ports 2 and 3, making it suitable for use as a standalone component or to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between ports 1 and 4 surpasses its setting, with port 4 being blockable to prevent shifting. Port 3 serves as a work port, while the direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities with identical flow paths. Key specifications include a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min). The valve incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. It is capable of modulating between two positions but is not bistable. Maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits. The valve's factory pressure settings are established at a flow rate of 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 DPBOCEN also includes practical features such as an adjustment screw internal hex size of 5/32 in. (4 mm) and a locknut torque range of 80-90 lbf\u00b7in (9-10 Nm). With these capabilities, this cartridge valve can effectively manage hydraulic circuits requiring precise modulation and control within specified parameters.

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 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.
