The Sun Hydraulics DRBPCBN (DRBPCBN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device that can be used independently 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 set value. Notably, the flow path between port 2 and port 3 is bidirectional, offering versatility in application. Additionally, this valve features low internal leakage and minimal pilot flow consumption due to its direct-acting design. Direct-acting and pilot-operated versions are interchangeable, fitting the same cavities with identical flow paths. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits, although the hydraulic operating limits are higher. The DRBPCBN incorporates Sun's floating style construction to minimize potential binding of internal parts caused by excessive installation torque or machining variations of cavity/cartridge interfaces. This model fits a T21A cavity and belongs to Series 1 with 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 5000 psi (350 bar). Valve leakage is minimal at less than 2 in\u00b3/min (30 cc/min) at standard fluid viscosity conditions. Adjustments can be made through clockwise turns to increase settings, with specific torque requirements for installation and locknut adjustments provided for optimal performance. Weighing .55 lb (.25 kg), this model comes with a Viton seal kit option for enhanced durability 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.
