The Sun Hydraulics DRBRXFN (Material Number: DRBRXFN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This valve can function independently or in conjunction with larger pilot-operated directional or logic cartridges. It shifts when the pressure differential between port 1 and port 4 exceeds the pre-set threshold, with a bidirectional flow path between port 2 and port 3. Notably, the design ensures low internal leakage and minimal pilot flow consumption. The valve is capable of modulating between two positions but is not bistable. Pressure at port 4 directly adds to the valve setting, while maximum pressure at port 3 should not exceed 3000 psi due to fatigue strength limits. The valve incorporates Sun's floating style construction to reduce the risk of binding from excessive installation torque or machining variations. It fits into a T-21A cavity, with a series capacity of up to 7 gpm (28 L/min) and can operate under a maximum pressure of 5000 psi (350 bar). Valve hex size measures at 7/8 inch (22.2 mm), and installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm). The maximum leakage rate is specified at 2 in\u00b3/min (30 cc/min) at an oil viscosity of 110 SUS (24 cSt). For maintenance, a Viton seal kit under part number 990021006 is available. This cartridge valve offers robustness and reliability for applications requiring precise modulation without bistability, making it suitable for various hydraulic systems where direct acting valves are preferred for their speed and stability.

Direct-acting, 3-way directional cartridges (3 to 4 open, 2 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.
- 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.
- 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.
