The Sun Hydraulics DRBOOSV (Material Number: DRBOOSV) is a direct-acting, three-way directional cartridge valve designed for moderate flow circuits. This versatile component functions as a switching device where one port is blocked while ports 2 and 3 are open, allowing bidirectional flow between these two ports. It can operate independently or in conjunction with larger pilot-operated or logic cartridges. The valve transitions when the pressure differential between port 1 and port 4 surpasses a specific threshold, with pressure at port 4 directly influencing the valve setting. Port 3 can be utilized as a work port, and the maximum pressure at this port should not exceed 3000 psi (210 bar) due to fatigue strength limitations. The DRBOOSV features low internal leakage and minimal pilot flow consumption due to its direct-acting design. It is interchangeable with pilot-operated versions, sharing cavity compatibility and flow path design. This model incorporates Sun's floating style construction to reduce the risk of internal binding from installation torque or machining variations. With a capacity of 7 gpm (28 L/min), it operates at a maximum pressure of 5000 psi (350 bar). The valve\u2019s leakage rate is limited to 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). Adjustments are made via an internal hex screw, with settings increasing clockwise over up to five turns. The DRBOOSV is not bistable but can modulate between two positions. Its installation requires specific torque settings: valve installation torque between 30-35 lbf ft (41-47 Nm) and locknut torque between 80-90 lbf in (9-10 Nm). This model weighs approximately .55 lb (.25 kg) and uses Viton seal kits for reliable performance in various applications.

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.
