The Sun Hydraulics DPBOCBV (DPBOCBV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can be utilized 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 a specified setting, with port 4 optionally blocked to prevent shifting. Port 3 is available for use as a work port. The valve's direct-acting and pilot-operated versions are interchangeable, fitting the same cavities and maintaining identical flow paths. Key specifications include a maximum pressure limit at port 3 of 3000 psi (210 bar) due to fatigue strength considerations, not hydraulic operating limits. The valve incorporates Sun's floating style construction, minimizing internal binding risks from excessive installation torque or machining variations. With a cavity size of T-21A and series designation of 1, this model features a capacity of up to 7 gpm (28 L/min) and factory pressure settings established at 4 gpm (15 L/min). It supports a maximum operating pressure of 5000 psi (350 bar) with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). The valve allows adjustment with up to five clockwise turns to increase the setting, featuring an internal hex size for adjustment screws of 5/32 in. (4 mm). The model weighs approximately .60 lb (0.30 kg) and utilizes Viton seal kits for optimal performance.

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.
