The Sun Hydraulics DPBOLAV (Material Number: DPBOLAV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This valve features one blocked port and two to three open ports, functioning as a switching device that can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the set threshold, with the option to block port 4 to prevent shifting. Port 3 serves as a work port and should not exceed a maximum pressure of 3000 psi (210 bar) due to fatigue strength limits. The DPBOLAV is capable of modulating between two positions and incorporates Sun's floating style construction to minimize internal binding from excessive torque or machining variations. It fits T21A cavities and offers a capacity of 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). The valve operates at a maximum pressure of 5000 psi (350 bar) and has a control pilot flow range of 7-10 in\u00b3/min (0.11-0.16 L/min). Valve installation requires specific torque settings, including an installation torque of 30-35 lbf\u00b7ft (41-47 Nm) and locknut torque of 80-90 lbf\u00b7in (9-10 Nm). With an adjustment screw internal hex size of 5/32 in. (4 mm), this model weighs approximately .60 lb (.30 kg) and includes a Viton seal kit option for enhanced durability.

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.
