The Sun Hydraulics DRBMCDN (Material Number: DRBMCDN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds a preset threshold. Notably, port 3 can be utilized as a work port, and the flow path between ports 2 and 3 is bidirectional. Due to its direct-acting design, the DRBMCDN offers low internal leakage and minimal pilot flow consumption. It 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 from excessive installation torque or machining variations in cavity/cartridge interfaces. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits, although the valve's hydraulic operating limits are higher. Its capacity is rated at 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure reaches up to 5000 psi (350 bar), while leakage is limited to a maximum of 2 in\u00b3/min (30 cc/min) at specified conditions. Installation specifications include a valve hex size of 7/8 inch (22.2 mm) and an installation torque range of 30-35 lbf-ft (41-47 Nm). For adjustment purposes, an internal hex size of 5/32 inch (4 mm) is provided for the adjustment screw, while the locknut requires a hex size of 9/16 inch (15 mm) with a torque specification of 80-90 lbf-in (9-10 Nm). The model weighs approximately .55 lb (.25 kg), and it utilizes Viton seal kits for cartridge sealing needs.

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.
