The Sun Hydraulics DRBPCWN (Material Number: DRBPCWN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It is versatile and can function independently or be used 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 pre-set threshold. 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. This design ensures minimal internal leakage and low pilot flow consumption due to its direct-acting nature. The DRBPCWN valve is interchangeable with pilot-operated versions, fitting the same cavities while maintaining identical flow paths. Its construction incorporates Sun's floating style to reduce the risk of internal parts binding from excessive torque or machining variations. The valve modulates between two positions rather than being bistable, offering flexibility in various applications. Key specifications include a cavity type of T-21A, series 1 capacity of up to 7 gpm (28 L/min), and a maximum operating pressure of 5000 psi (350 bar). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength constraints rather than hydraulic limits. The valve features an adjustment mechanism that requires up to five clockwise turns to increase the setting, with specific torque requirements for installation and adjustment components. Additionally, it weighs approximately .55 lb (0.25 kg) and includes a Viton seal kit for maintenance purposes.

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.
