The Sun Hydraulics DRBBKBN (Material Number: DRBBKBN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. With a capacity of 7 gpm (28 L/min) and maximum operating pressure of 5000 psi (350 bar), it serves as an efficient switching device, either independently or to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 3 surpasses the set threshold, with pressure at port 3 being directly additive to the valve setting. This feature may limit the use of port 3 as a work port in certain circuits; alternatively, a 4-port version could be considered for such applications. The direct-acting design ensures low internal leakage and minimal pilot flow consumption. Notably, these cartridges are interchangeable with pilot-operated versions, sharing identical cavities and flow paths. The valve is not bistable but can modulate between two positions, featuring Sun's floating style construction to mitigate potential binding from excessive installation torque or cavity machining variations. Installation specifics include a cavity size T-11A, series 1 designation, factory pressure settings established at 4 gpm (15 L/min), and maximum valve leakage at 2 in\u00b3/min (30 cc/min). It requires an installation torque of 30\u201335 lbf ft (41\u201347 Nm) with adjustment via an internal hex screw sized at 5/32 in (4 mm). The locknut hex size is set at 9/16 in (15 mm) with a locknut torque of 80\u201390 lbf in (9\u201310 Nm). The model weighs approximately .60 lb (.30 kg) and utilizes Viton seal kits for enhanced durability.

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.
