The Sun Hydraulics DPBOCEV (DPBOCEV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can be used independently or to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds its set threshold, with options to block port 4 and utilize port 3 as a work port. The DPBOCEV is interchangeable with direct-acting versions, sharing the same cavity and flow paths. Its floating style construction minimizes internal part binding due to variations in installation torque or machining. The valve has a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength considerations. For those concerned with pilot flow consumption when pilot pressure exceeds valve settings, switching to the direct-acting version may be beneficial. Additional specifications include a control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), maximum valve leakage of 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar), and an adjustment range requiring up to five clockwise turns to increase settings. The valve's hex size measures at .78 inches (22.2 mm), with an installation torque requirement between 30 and 35 lbf\u00b7ft (41 and 47 Nm). It also features an internal hex size of .156 inches (4 mm) for adjustment screws, a locknut hex size of .562 inches (15 mm), and locknut torque between 80 and 90 lbf\u00b7in (9 and 10 Nm). Weighing .60 lb (.30 kg), this model includes Viton seal kits available for replacement needs.

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.
