The Sun Hydraulics DRBMLWN (DRBMLWN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This component can function independently or in conjunction with larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the pre-set threshold. Port 3 serves as a work port, and the flow path between ports 2 and 3 is bidirectional, enhancing its versatility in various applications. The direct-acting design ensures low internal leakage and minimal pilot flow consumption, making it efficient for systems requiring precise control. Additionally, these valves are interchangeable with pilot-operated versions, sharing the same cavities and flow paths. The DRBMLWN incorporates Sun's floating style construction to mitigate potential binding of internal parts due to excessive installation torque or machining variations in cavity/cartridge interfaces. It fits into cavity T21A and belongs to series 1 with a capacity of up to 7 gpm (28 L/min). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Despite its robust design, the maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength constraints rather than hydraulic operating limits. For adjustments, users can increase settings by turning clockwise up to five turns. The valve features a hex size of 7/8 inch (22.2 mm) for installation torque ranging from 30 to 35 lbf ft (41 to 47 Nm). It also includes an adjustment screw internal hex size of 5/32 inch (4 mm) and a locknut hex size of 9/16 inch (15 mm), with locknut torque specified between 80 to 90 lbf in (9 to 10 Nm). The model weighs .55 lb (.25 kg) and comes equipped with a Viton seal kit for enhanced durability.

Normally open, direct-acting, 2-way directional cartridges 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.
- Port 3 can be used as a work port.
- 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.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Pressure at port 4 is directly additive to the setting of the valve.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- 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.
