The Sun Hydraulics DPBOCWN (DPBOCWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold. Notably, port 4 can be blocked to prevent shifting, and port 3 serves as a work port. The DPBOCWN is interchangeable with direct-acting versions, fitting the same cavities and maintaining identical flow paths. It features Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. The valve has a capacity of 7 gpm (28 L/min) and can handle a maximum operating pressure of up to 5000 psi (350 bar). For optimal performance, factory pressure settings are established at 4 gpm (15 L/min). The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limitations rather than hydraulic operating constraints. Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), while maximum valve leakage is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustments are made using an internal hex screw with a locknut for securing settings, requiring specific torque values for installation and adjustment operations. The device weighs approximately .60 lb (.30 kg) and utilizes Viton seals for reliable performance under various conditions. This valve is not bistable but modulates between two positions, making it suitable for applications where precise control over fluid direction is essential.

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.
