The Sun Hydraulics DRBRKNV (DRBRKNV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses its setting, with a maximum setting of 800 psi (55 bar). The valve's maximum operating pressure is rated at 5000 psi (350 bar), and it has a capacity of handling flows up to 7 gpm (28 L/min). The flow path between port 2 and port 3 is bidirectional, allowing for versatile application in hydraulic systems. Notably, the valve features low internal leakage and minimal pilot flow consumption due to its direct-acting design. The DRBRKNV incorporates Sun's floating style construction to reduce the risk of internal parts binding from excessive installation torque or machining variations. It is not bistable and can modulate between two positions, offering precise control in hydraulic circuits. The valve is installed in a T21A cavity with specific installation torques: the valve requires a torque of 30-35 lbf ft (41-47 Nm), while the locknut needs a torque of 80-90 lbf in (9-10 Nm). Additionally, it uses Viton seal kits for reliable sealing performance. This cartridge valve is suitable for applications requiring fast response times and stable operation under varying conditions.

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.
