The Sun Hydraulics DPBOCJV (DPBOCJV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve shifts based on the pressure differential between port 1 and port 4, with the ability 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 due to their identical cavity fit and flow paths. The design ensures that pressure at port 4 directly adds to the valve's setting, allowing for modulation between two positions rather than bistable operation. The valve's maximum pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength limits, though it operates hydraulically up to a maximum of 5000 psi (350 bar). It features a capacity of 7 gpm (28 L/min) with factory pressure settings established at 4 gpm (15 L/min). Control pilot flow ranges from 7-10 in\u00b3/min (0.11-0.16 L/min), while maximum leakage is limited to 1 in\u00b3/min at 110 SUS (24 cSt). The valve incorporates Sun's floating style construction, minimizing internal binding risks due to installation torque or machining variations. Installation specifications include a cavity size of T21A, series number 1, and an installation torque requirement of 30-35 lbf\u00b7ft (41-47 Nm). Adjustments can be made using an internal hex size of 5/32 in. (4 mm), with locknut torque set between 80-90 lbf\u00b7in. (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and utilizes Viton seal kits for maintenance requirements.

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.
