The Sun Hydraulics DRBBLBN (DRBBLBN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be utilized to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses a predetermined setting, with pressure at port 3 directly adding to this setting. Due to this characteristic, port 3 may not be suitable as a work port in certain circuits; however, a 4-port version of the valve is available for such applications. Notably, the direct-acting design ensures low internal leakage and minimal pilot flow consumption. Additionally, this valve is interchangeable with pilot-operated versions as they share the same cavities and flow paths. The DRBBLBN is capable of modulating between two positions rather than being bistable, incorporating Sun's floating style construction which minimizes internal part binding due to excessive installation torque or machining variations. It features a T-11A cavity and has a capacity of 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with maximum valve leakage at 2 in\u00b3/min (30 cc/min). For adjustments, it requires approximately 5.5 clockwise turns to increase settings, and key dimensions include a valve hex size of .78 inches (22.2 mm) and an installation torque range of 30 - 35 lbf\u00b7ft (41 - 47 Nm). The model weighs .60 lb (.30 kg) and uses Viton seal kits for enhanced durability under various conditions.

Normally closed, 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.
