The Sun Hydraulics DRBMLEV (DRBMLEV) is a normally open, direct-acting, 2-way directional cartridge valve designed for use in moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds the preset setting, with port 3 available as a work port. It features a bidirectional flow path between ports 2 and 3, ensuring flexibility in various applications. This model utilizes Sun's floating style construction to reduce the risk of internal component binding due to installation torque or machining variations. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min), it is suitable for demanding hydraulic systems. The valve is not bistable but can modulate between two positions, offering reliable performance in dynamic environments. The DRBMLEV incorporates low internal leakage and low pilot flow consumption due to its direct-acting design. It is interchangeable with pilot-operated versions, fitting the same cavities and maintaining consistent flow paths. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limitations. Additional specifications include a cavity size of T-21A, series number 1, factory pressure settings established at 4 gpm (15 L/min), and an adjustment range allowing for up to five clockwise turns to increase setting. The valve's compact design features a hex size of 7/8 inches (22.2 mm) for easy installation with an installation torque of 30-35 lbf\u00b7ft (41-47 Nm).

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.
