The Sun Hydraulics DRBCKSN (DRBCKSN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It features one blocked port and an open connection between ports 2 and 3, making it ideal for applications that require switching capabilities. This valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. The operational shift occurs 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. Due to this characteristic, port 3 may not be suitable as a work port in some circuits; however, a four-port version of this valve could address such concerns. The DRBCKSN model is notable for its low internal leakage and minimal pilot flow consumption, attributes stemming from its direct-acting design. Both direct-acting and pilot-operated versions are interchangeable within their cavities while sharing identical flow paths. This particular model is not bistable but can modulate between two positions as needed. Sun's floating style construction reduces the risk of internal component binding due to excessive installation torque or machining variations in cavity-cartridge interfaces. Key specifications include a T11A cavity, Series 1 designation, a capacity of 7 gpm (28 L/min), and a maximum operating pressure of 5000 psi (350 bar). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with maximum valve leakage at only 2 in\u00b3/min (30 cc/min). Installation requires specific torque values: the valve hex size is 7/8 inch (22.2 mm), with an installation torque range of 30\u201335 lbf\u00b7ft (41\u201347 Nm). The adjustment screw features an internal hex size of 5/32 inch (4 mm), complemented by a locknut hex size of 9/16 inch (15 mm) requiring a torque range of 80\u201390 lbf\u00b7in (9\u201310 Nm). The model weighs .60 lb (.30 kg) and utilizes Viton seal kits available under part number 990011006.

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