The Sun Hydraulics DPBOCJN (DPBOCJN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold, with port 4 capable of being blocked to prevent shifting. Port 3 serves as a work port and is suitable for applications where the maximum pressure does not exceed 3000 psi (210 bar) due to fatigue strength limits. The DPBOCJN valve features interchangeable direct-acting and pilot-operated versions that fit the same cavities and maintain identical flow paths. The valve incorporates Sun's floating style construction, which minimizes internal part binding caused by excessive installation torque or machining variations. With a maximum operating pressure of up to 5000 psi (350 bar), this valve supports a capacity of up to 7 gpm (28 L/min) and has factory pressure settings established at 4 gpm (15 L/min). The control pilot flow ranges between 7-10 in\u00b3/min (0,11 - 0,16 L/min), while its maximum leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The adjustment mechanism allows for fine-tuning with up to five clockwise turns needed to increase the setting. The DPBOCJN model weighs .60 lb (.30 kg) and requires an installation torque between 30 - 35 lbf\u00b7ft (41 - 47 Nm). It uses a Viton seal kit for optimal performance and longevity. This non-bistable valve is capable of modulating between two positions, making it ideal for applications requiring precise control over hydraulic flow direction without bistable switching characteristics.

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.
