The Sun Hydraulics DRBRONN (DRBRONN) 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 directional or logic cartridges. It shifts when the pressure differential between port 1 and port 4 surpasses the set threshold, with a maximum setting of 800 psi (55 bar). The valve features a bidirectional flow path between ports 2 and 3 and is built to handle a maximum operating pressure of up to 5000 psi (350 bar), while the pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. With a capacity of 7 gpm (28 L/min), this cartridge valve boasts low internal leakage and pilot flow consumption thanks to its direct-acting design. Furthermore, it incorporates Sun's floating style construction, which reduces the risk of internal parts binding from excessive installation torque or machining variations. The DRBRONN is not bistable but can modulate between two positions, making it suitable for applications requiring precise control. It fits into cavity T21A and requires an installation torque of 30-35 lbf ft (41-47 Nm). The valve's hex size is 7/8 in. (22.2 mm), while the locknut hex size measures at 9/16 in. (15 mm). For maintenance, a Viton seal kit with part number 990021006 is available.

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.
