The Sun Hydraulics DRBMLBV (DRBMLBV) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds its set threshold. Port 3 serves as a work port, with a bidirectional flow path between ports 2 and 3. Thanks to its direct-acting design, this cartridge offers low internal leakage and minimal pilot flow consumption, making it both efficient and reliable. The DRBMLBV is interchangeable with pilot-operated versions, sharing the same cavities and flow paths. The valve incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or machining variations in the cavity/cartridge. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limitations. It features a capacity of 7 gpm (28 L/min) and factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with a maximum valve leakage at 110 SUS (24 cSt) of 2 in\u00b3/min (30 cc/min). For installation, the valve requires a torque of 30-35 lbf\u00b7ft (41-47 Nm), with an adjustment screw internal hex size of 5/32 in. (4 mm). The locknut has a hex size of 9/16 in. (15 mm) and requires a torque of 80-90 lbf\u00b7in. (9-10 Nm). The model weighs .55 lb (.25 kg) and uses Viton seal kits for optimal performance in various applications.

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.
