The Sun Hydraulics DRBOKSN (Material Number: DRBOKSN) 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 or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 surpasses the set threshold, providing bidirectional flow paths between ports 2 and 3, as well as ports 1 and 2. Port 3 serves as a work port, with a maximum pressure limit of 3000 psi (210 bar) due to fatigue strength constraints. The DRBOKSN features low internal leakage and minimal pilot flow consumption thanks to its direct-acting design. It is interchangeable with pilot-operated versions, sharing the same cavities and flow paths. The valve incorporates Sun's floating style construction to reduce the likelihood of internal parts binding from excessive installation torque or cavity-cartridge machining variations. The cavity type for this model is T-21A, with a series designation of 1 and 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), with a maximum operating pressure of up to 5000 psi (350 bar). The maximum valve leakage at an oil viscosity of 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min). For adjustments, the valve requires up to five clockwise turns to increase the setting, using an internal hex size adjustment screw measuring ^5/32 in. (4 mm). Installation torque ranges between 30 - 35 lbf ft (41 - 47 Nm), while the locknut hex size measures ^9/16 in. (15 mm) with a locknut torque specification of 80 - 90 lbf in. (9 -10 Nm). The model weighs approximately .55 lb (.25 kg) and uses Viton seal kits for optimal performance.

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 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.
