The Sun Hydraulics DRBPCEN (DRBPCEN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can be utilized independently or 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 surpasses the preset value. Notably, port 3 serves as a work port, and the flow paths between ports 1 and 2, as well as ports 2 and 3, are bidirectional. Due to its direct-acting design, the DRBPCEN offers low internal leakage and minimal pilot flow consumption. Additionally, this valve can interchange with pilot-operated versions without requiring modifications to cavities or flow paths. The DRBPCEN is engineered with Sun's floating style construction, which helps prevent internal part binding from excessive installation torque or machining variations in cavity/cartridge interfaces. It features a T-21A cavity, has a capacity of 7 gpm (28 L/min), and is factory pressure set at a flow rate of 4 gpm (15 L/min). The maximum operating pressure for this valve is rated at 5000 psi (350 bar), while maximum allowable pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. The valve's adjustment settings include an increase in setting through clockwise turns up to a total of five turns. The installation torque ranges from 30 to 35 lbf-ft (41 to 47 Nm), with an adjustment screw internal hex size of \\(5/32\\) in. (4 mm). The locknut requires a torque of between 80 to 90 lbf-in. (9 to 10 Nm). Weighing .55 lb (.25 kg), the DRBPCEN also includes a Viton seal kit for durability and reliability in various applications.

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.
