The Sun Hydraulics DRBROSV (Material Number: DRBROSV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device, capable of operating independently or actuating larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 surpasses the set threshold, with an upper limit of 800 psi (55 bar). The maximum allowable pressure at port 3 is restricted to 3000 psi (210 bar) due to fatigue strength constraints. Notably, the flow path between ports 2 and 3 is bidirectional, ensuring versatility in application. This valve features low internal leakage and minimal pilot flow consumption owing to its direct-acting design. It is not bistable but can modulate between two positions. The Sun floating style construction minimizes the risk of internal part binding caused by excessive installation torque or cavity-cartridge machining variations. The DRBROSV fits into cavity T21A and belongs to series 1 with a capacity of 7 gpm (28 L/min). It operates at a maximum pressure of 5000 psi (350 bar) with a leakage rate capped at 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). Adjustments are made by turning clockwise, with up to five turns available for setting increases. Installation requires a valve hex size of 7/8 inch (22.2 mm) and torque between 30\u201335 lbf\u00b7ft (41\u201347 Nm), while the locknut hex size is set at 9/16 inch (15 mm) with torque specifications of 80\u201390 lbf\u00b7in (9\u201310 Nm). A Viton seal kit is available under part number: 990021006 for maintenance or replacement needs.

Direct-acting, 3-way directional cartridges (3 to 4 open, 2 blocked) 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.
- Note: 800 psi (55 bar) is the highest setting possible with this valve.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- 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.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- 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.
