The Sun Hydraulics DRBAKBN (DRBAKBN) is a normally open, direct-acting, 2-way directional cartridge valve designed for use in moderate flow circuits. It serves as a switching device that can operate independently or in conjunction with larger pilot-operated directional cartridges or logic cartridges. The valve activates when the pressure differential between port 1 and port 3 surpasses the set threshold, with pressure at port 3 directly influencing the valve setting. As such, port 3 may not be suitable as a work port in certain circuits; in such cases, a 4-port version might be preferable. The direct-acting design ensures low internal leakage and minimal pilot flow consumption, making it highly efficient. This particular valve is not bistable and can modulate between two positions as needed. It features Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or variations in cavity-cartridge machining. With a cavity size of T-11A and a flow capacity of 7 gpm (28 L/min), this Series 1 valve operates at a maximum pressure of 5000 psi (350 bar). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). The maximum valve leakage at viscosity levels of 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min). The DRBAKBN model requires an installation torque between 30 and 35 lbf\u00b7ft (41 to 47 Nm), with an adjustment screw internal hex size of 5/32 inches (4 mm) and locknut hex size of 9/16 inches (15 mm). The locknut torque ranges from 80 to 90 lbf\u00b7in (9 to 10 Nm). Weighing approximately .60 lb (.30 kg), this cartridge valve also comes with an optional Viton seal kit for enhanced durability.

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.
