The Sun Hydraulics DRBOLBV (Material Number: DRBOLBV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It serves as a switching device where one port is blocked while ports two and three are open, making it versatile for various hydraulic applications. This valve is capable of actuating larger pilot-operated directional or logic cartridges and shifts when the pressure differential between port 1 and port 4 exceeds its setting. Notably, the flow path between ports 2 and 3 is bidirectional, as is the path between ports 1 and 2, allowing flexible operation within hydraulic systems. The DRBOLBV features low internal leakage and minimal pilot flow consumption due to its direct-acting design. It fits seamlessly into the T-21A cavity series with a capacity of up to 7 gpm (28 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). The valve incorporates Sun's floating style construction to reduce potential internal binding due to installation torque or machining variations. For optimal performance, it is important to limit maximum pressure at port 3 to 3000 psi (210 bar) because of fatigue strength limits. The valve's adjustment range allows for fine-tuning with up to five full clockwise turns to increase the setting. Its robust construction includes a hex size of 7/8 inch (22.2 mm) for easy installation torque management between 30-35 lbf ft (41-47 Nm). Additionally, it comes with Viton seal kits for reliable sealing performance in demanding environments. Overall, the Sun Hydraulics DRBOLBV provides precise control in hydraulic circuits requiring dependable switching capabilities with low leakage and efficient flow management.

Direct-acting, 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 3 can be used as a work port.
- The flow path between port 2 and port 3 is bidirectional.
- Because of their direct-acting design, these cartridges feature low internal leakage and low pilot flow consumption.
- 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.
- The flow path between port 1 and port 2 is bidirectional.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- 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.
