The Sun Hydraulics DRBDKSN (DRBDKSN) is a direct-acting, 3-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 a pre-set threshold, with pressure at port 3 directly adding to the valve's setting. Due to this characteristic, port 3 may not be suitable as a work port in certain circuits; in such cases, a 4-port version might be more appropriate. Notably, this valve is not bistable and can modulate between its two positions. The DRBDKSN features low internal leakage and minimal pilot flow consumption due to its direct-acting design. Both direct-acting and pilot-operated versions of these valves are interchangeable, sharing the same cavities and flow paths. The valve incorporates Sun's floating style construction, reducing the risk of internal parts binding from excessive installation torque or machining variations. Key specifications include a T-11A cavity type, series 1 classification, and a capacity of 7 gpm (28 L/min). It has a maximum operating pressure of 5000 psi (350 bar) and exhibits maximum valve leakage of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). The valve requires an installation torque of 30\u201335 lbf\u00b7ft (41\u201347 Nm) with adjustment facilitated by an internal hex screw size of 5/32 inch (4 mm). Additionally, it has a locknut hex size of 9/16 inch (15 mm) with a corresponding torque specification of 80\u201390 lbf\u00b7in (9\u201310 Nm). Weighing .60 lb (.30 kg), the DRBDKSN is compatible with Viton seal kits for enhanced durability in various applications.

Direct-acting, 3-way directional cartridges (1 to 2 open, 3 blocked) 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.
