The Sun Hydraulics DPBOLWV (DPBOLWV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This valve features one blocked port and an open path between ports 2 and 3, making it suitable for applications where switching devices are required to actuate larger pilot-operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds a predetermined setting, with the option to block port 4 to prevent shifting. Port 3 can be utilized as a work port, allowing for versatile integration into hydraulic systems. Direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities and offering identical flow paths. The maximum pressure at port 3 is limited to 3000 psi due to fatigue strength limits, although the valve can operate up to a maximum pressure of 5000 psi. It has a capacity of handling flow rates up to 7 gpm (28 L/min) with factory pressure settings established at 4 gpm (15 L/min). The valve incorporates Sun's floating style construction, reducing the risk of internal parts binding from excessive installation torque or machining variations. This model is not bistable but can modulate between two positions. Adjustments can be made with up to five clockwise turns to increase settings, using an internal hex size adjustment screw. The DPBOLWV also includes a Viton seal kit for maintenance purposes. With its robust design and versatile application capabilities, this valve is ideal for hydraulic systems requiring reliable control over moderate flow circuits.

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.
