The Sun Hydraulics DRBROEN (DRBROEN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to actuate larger pilot-operated directional or logic cartridges. Its operation is triggered when the pressure differential between port 1 and port 4 surpasses the set threshold, with an upper limit of 800 psi (55 bar). The valve is engineered to handle a maximum operating pressure of 5000 psi (350 bar), with port 3's pressure capped at 3000 psi (210 bar) due to fatigue strength considerations. Featuring a bidirectional flow path between ports 2 and 3, this cartridge ensures low internal leakage and minimal pilot flow consumption due to its direct-acting design. Notably, the valve is not bistable; it modulates between two positions as required. It incorporates Sun's floating style construction, which reduces the risk of internal binding caused by excessive installation torque or machining variations in the cavity/cartridge interface. The DRBROEN fits into a T21A cavity and offers a capacity of up to 7 gpm (28 L/min). For optimal performance, it requires specific installation torques: valve hex size at 7/8 inch (22.2 mm) with a torque of 30\u201335 lbf ft (41\u201347 Nm) and locknut hex size at 9/16 inch (15 mm) with a torque of 80\u201390 lbf in (9\u201310 Nm). Additionally, it comes equipped with a Viton seal kit for reliable sealing performance.

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.
