The Sun Hydraulics DRBNOSN (DRBNOSN) is a normally closed, direct-acting, 2-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. It operates by shifting when the pressure differential between port 1 and port 4 exceeds a specific setting. Notably, port 3 can serve as a work port, and the flow path between port 2 and port 3 is bidirectional, allowing for flexible application in various systems. The direct-acting design ensures low internal leakage and minimal pilot flow consumption. The DRBNOSN valve features interchangeable direct-acting and pilot-operated versions that fit the same cavities and share identical flow paths, enhancing its adaptability across different setups. The pressure at port 4 directly adds to the valve's setting, while the maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limitations. This valve incorporates Sun's floating style construction, which minimizes internal parts binding caused by excessive installation torque or cavity-cartridge machining variations. Additional specifications include a T21A cavity with a series capacity of 7 gpm (28 L/min), factory pressure settings established at 4 gpm (15 L/min), and a maximum operating pressure of 5000 psi (350 bar). The valve's maximum leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min). Adjustments are made via an internal hex screw with clockwise turns increasing the setting. The DRBNOSN weighs .55 lb (.25 kg) and uses Viton seal kits for cartridge sealing.

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 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.
- 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.
