The Sun Hydraulics DRBAKSN (DRBAKSN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used 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 the pre-set threshold, with pressure at port 3 directly contributing to this setting. Due to its direct-acting design, the DRBAKSN offers low internal leakage and minimal pilot flow consumption, making it efficient for various applications. It is interchangeable with pilot-operated versions, sharing identical cavities and flow paths. The DRBAKSN features Sun\u2019s floating style construction to minimize the risk of internal parts binding from excessive installation torque or machining variations. It fits into a T-11A cavity and has a capacity of up to 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). The valve can handle a maximum operating pressure of 5000 psi (350 bar) and exhibits a maximum leakage rate of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). Adjustments are made via an internal hex screw, requiring up to five clockwise turns to increase settings. Weighing just .60 lb (.30 kg), this compact valve has specific installation requirements: a hex size of .78 in. (22.2 mm) for the valve body, with installation torque between 30 and 35 lbf\u00b7ft (41\u201347 Nm). The locknut requires a hex size of .916 in. (15 mm) and torque between 80 and 90 lbf\u00b7in (9\u201310 Nm). With its robust construction and reliable performance, the DRBAKSN is suitable for applications requiring precise modulation between two positions without bistability concerns.

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.
