The Sun Hydraulics DRBMLDN (Material Number: DRBMLDN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device and can be used independently 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 set threshold, with port 3 available for use as a work port. Its design allows for bidirectional flow between ports 2 and 3, ensuring low internal leakage and minimal pilot flow consumption. This makes the valve efficient in applications requiring precise modulation between two positions rather than bistability. The DRBMLDN features a maximum operating pressure of 5000 psi (350 bar) and should maintain a maximum pressure at port 3 of no more than 3000 psi (210 bar) due to fatigue strength limitations. With a capacity of 7 gallons per minute (28 liters per minute), this valve is suitable for various hydraulic systems requiring reliable directional control. It incorporates Sun's floating-style construction, which minimizes potential internal part binding caused by excessive installation torque or machining variations. The valve's installation specifications include a cavity T-21A, series 1 configuration, with factory pressure settings established at a flow rate of 4 gpm (15 L/min). Adjustments to increase settings require up to five clockwise turns on the adjustment screw. The DRBMLDN weighs approximately .55 lbs (0.25 kg) and includes Viton seals as part of its cartridge seal kit. This robust design ensures stability and reliability in demanding environments where precise hydraulic control is essential.

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.
