The Sun Hydraulics DRBOOBV (Material Number: DRBOOBV) is a direct-acting, 3-way directional cartridge valve designed to manage moderate flow circuits effectively. This versatile component can function independently or in conjunction with larger pilot-operated or logic cartridges, making it ideal for a variety of hydraulic applications. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the preset value, with port 3 serving as a work port. The valve offers bidirectional flow paths between ports 2 and 3, as well as between ports 1 and 2, ensuring flexibility in circuit design. This model's direct-acting design results in low internal leakage and minimal pilot flow consumption, enhancing efficiency. It is interchangeable with pilot-operated versions due to its consistent cavity fit and flow path design. Notably, pressure at port 4 adds directly to the valve's setting, although the maximum pressure at port 3 should not exceed 3000 psi due to fatigue strength limitations. Key specifications include a capacity of 7 gpm (28 L/min), maximum operating pressure of 5000 psi (350 bar), and a factory pressure setting established at 4 gpm (15 L/min). The valve features Sun's floating style construction to reduce the risk of internal binding from excessive installation torque or machining variations. With an adjustment range that increases with clockwise turns up to five full rotations, this valve provides precise control for various hydraulic systems. Additionally, it includes Viton seals for reliability in diverse environments.

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.
