The Sun Hydraulics DRBACBN (DRBACBN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It is versatile in application, functioning independently or as an actuator for larger pilot-operated directional or logic cartridges. This valve shifts when the pressure differential between port 1 and port 3 exceeds its set threshold, with pressure at port 3 directly adding to the setting, which may limit its use as a work port in certain circuits. For such cases, a 4-port version might be more suitable. Its direct-acting design ensures low internal leakage and minimal pilot flow consumption. Notably, direct-acting and pilot-operated versions of these valves are interchangeable due to their compatibility with the same cavities and flow paths. The DRBACBN is not bistable; it can modulate between two positions as needed. It incorporates Sun's floating style construction to reduce the risk of internal part binding from excessive installation torque or cavity-cartridge machining variations. The valve fits into a T-11A cavity and belongs to series 1 with a capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). Maximum valve leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min). Adjustment for increasing settings involves up to five complete clockwise turns. The valve has a hex size of .78 inches (22.2 mm) and requires an installation torque of 30\u201335 lbf\u00b7ft (41\u201347 Nm). The adjustment screw has an internal hex size of .156 inches (4 mm), while the locknut hex size is .5625 inches (15 mm), needing a torque of 80\u201390 lbf\u00b7in (9\u201310 Nm). The model weight is approximately .60 lb (.30 kg), with Viton seal kits available under part number 990011006.

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 3 exceeds the setting.
- Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution.
- 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.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- 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.
