The Sun Hydraulics DRBMLDV (DRBMLDV) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses a predefined setting, with port 3 available for use as a work port. The bidirectional flow path between ports 2 and 3 enhances its functionality across various applications. Featuring low internal leakage and minimal pilot flow consumption due to its direct-acting design, this valve is interchangeable with pilot-operated versions, sharing the same cavities and flow paths. The DRBMLDV incorporates Sun's floating style construction to reduce the likelihood of internal binding from excessive installation torque or cavity-cartridge machining variations. It is capable of modulating between two positions rather than being bistable, which adds to its adaptability in different circuit configurations. With a capacity of handling up to 7 gallons per minute (28 liters per minute) and a maximum operating pressure of 5000 psi (350 bar), it is robust enough for demanding applications while maintaining precision control with factory pressure settings established at 4 gpm (15 L/min). The valve's installation specifications include a hex size of 7/8 inch (22.2 mm) and an installation torque range of 30-35 lbf ft (41-47 Nm). Additionally, it features adjustment capabilities through an internal hex screw size of 5/32 inch (4 mm), with locknut torque parameters set at 80-90 lbf in (9-10 Nm). The DRBMLDV weighs approximately .55 lb (.25 kg) and utilizes Viton seal kits for optimal performance in various hydraulic systems.

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.
