The Sun Hydraulics DRBMCBN (Material Number: DRBMCBN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It serves as a switching device, either operating independently or actuating larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 surpasses the set threshold. Notably, port 3 can function as a work port, and the flow path between ports 2 and 3 is bidirectional. Thanks to its direct-acting design, this cartridge features low internal leakage and minimal pilot flow consumption. The DRBMCBN model is interchangeable with both direct-acting and pilot-operated versions, sharing cavity fitment and flow paths. Pressure at port 4 directly adds to the valve's setting; however, maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limitations rather than hydraulic operating constraints. The valve incorporates Sun's floating style construction to reduce the risk of internal component binding from excessive installation torque or machining variations in cavity/cartridge interfaces. It fits into a T-21A cavity, belongs to series 1 with a capacity of 7 gpm (28 L/min), and has factory pressure settings established at 4 gpm (15 L/min). Its maximum operating pressure is rated at 5000 psi (350 bar), with a maximum valve leakage of 2 in\u00b3/min (30 cc/min) at standard viscosity. The adjustment screw allows for setting increases through clockwise turns up to a total of five turns. The valve features specific installation torques: hex size of 7/8 in. (22.2 mm) with torque values between 30 - 35 lbf\u00b7ft (41 - 47 Nm), an internal hex size for adjustment screws of 5/32 in. (4 mm), locknut hex size of 9/16 in. (15 mm), and locknut torque ranging from 80 - 90 lbf\u00b7in. (9 -10 Nm). The model weighs approximately .55 lb (.25 kg) and utilizes Viton seal kits identified by part number: 990021006.

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.
