The Sun Hydraulics DRBPKSN (DRBPKSN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold. The valve features bidirectional flow paths between port 1 and port 2, as well as between port 2 and port 3, with port 3 serving as a work port if needed. The design ensures low internal leakage and minimal pilot flow consumption due to its direct-acting nature. The DRBPKSN's maximum operating pressure is rated at 5000 psi (350 bar), while it maintains a capacity of up to 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). The valve incorporates Sun's floating style construction, reducing the risk of internal parts binding from excessive installation torque or machining variations in the cavity/cartridge. It fits T-21A cavities and is interchangeable with other direct-acting and pilot-operated versions due to shared cavity dimensions and flow paths. For installation, the valve requires an installation torque of between 30 to 35 lbf ft (41 to 47 Nm), with an adjustment screw internal hex size of 5/32 in. (4 mm) and a locknut hex size of 9/16 in. (15 mm). The locknut should be torqued between 80 to 90 lbf in. (9 to 10 Nm). The product weighs approximately .55 lb (.25 kg) and uses Viton seal kits for optimal performance under various conditions.

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 4 exceeds the setting.
- Port 3 can be used as a work port.
- The flow path between port 2 and port 3 is bidirectional.
- 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.
- Pressure at port 4 is directly additive to the setting of the valve.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- The flow path between port 1 and port 2 is bidirectional.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- 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.
