The Sun Hydraulics DRBRONV (Material Number: DRBRONV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can be used independently or to actuate larger pilot-operated or logic cartridges. It shifts when the pressure differential between port 1 and port 4 exceeds its set value, with a maximum setting of 800 psi (55 bar). The valve features a bidirectional flow path between ports 2 and 3 and provides low internal leakage and pilot flow consumption due to its direct-acting design. It is capable of modulating between two positions but is not bistable. This cartridge incorporates Sun's floating style construction to minimize internal binding caused by excessive installation torque or cavity-cartridge machining variations. With a capacity of 7 gpm (28 L/min) and a maximum operating pressure of 5000 psi (350 bar), it is robust enough for demanding applications. The valve's maximum leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min). Installation requires a cavity T-21A, with specific torque settings for the valve hex size of 7/8 in. (22.2 mm) at 30-35 lbf ft (41-47 Nm), and locknut hex size of 9/16 in. (15 mm) at 80-90 lbf in. (9-10 Nm). The adjustment involves several clockwise turns to increase the setting, with Viton seal kits available under part number 990021006. Overall, the Sun Hydraulics DRBRONV offers reliable performance with minimal maintenance, making it suitable for various hydraulic systems requiring efficient flow control and pressure modulation.

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.
