The Sun Hydraulics DRBRLSN (DRBRLSN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds its setting, with a maximum setting of 800 psi (55 bar). The valve's design ensures low internal leakage and minimal pilot flow consumption, although it is not bistable and can modulate between two positions. Its construction features Sun's floating style to reduce the risk of internal binding from excessive installation torque or machining variations. With a capacity of 7 gpm (28 L/min) and a maximum operating pressure of 5000 psi (350 bar), it offers reliable performance within these parameters. The bidirectional flow path between ports 2 and 3 adds to its flexibility in application. Installation requires specific torques: the valve hex size is 7/8 inch (22.2 mm) with an installation torque of 30-35 lbf ft (41-47 Nm), while the locknut hex size is 9/16 inch (15 mm) with a torque of 80-90 lbf in (9-10 Nm). A Viton seal kit is available for maintenance needs, ensuring durability under various 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.
