The Sun Hydraulics DRBNXFN (Material Number: DRBNXFN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for use in moderate flow hydraulic circuits. This versatile component can function independently or be utilized to actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds the specified setting. Notably, port 3 can serve as a work port, and the flow path between ports 2 and 3 is bidirectional. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min), this valve is engineered for durability and efficiency. It incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or cavity-cartridge machining variations. The design ensures low internal leakage and minimal pilot flow consumption, making it an efficient choice for various applications. The valve's direct-acting design allows for quick response times, while its interchangeable nature with pilot-operated versions provides flexibility in system design. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating constraints. Additionally, the DRBNXFN features a valve hex size of 7/8 inches (22.2 mm) and requires an installation torque of 30-35 lbf ft (41-47 Nm). Its compact model weight of .55 lb (0.25 kg) facilitates easy integration into existing systems. This cartridge fits into cavity T-21A, belongs to series 1, and has factory pressure settings established at a flow rate of 4 gpm (15 L/min). The maximum valve leakage at viscosity levels of 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min), ensuring reliable performance across various operational conditions.

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.
