The Sun Hydraulics DRBPLAV (DRBPLAV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It features a configuration where ports 1 to 2 are open, and port 3 is blocked, making it suitable for use as a standalone unit or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds the set threshold. Port 3 can serve as a work port, and the flow path between ports 2 and 3 is bidirectional. This design ensures low internal leakage and minimal pilot flow consumption. The DRBPLAV model is interchangeable with other direct-acting and pilot-operated versions due to its compatibility with the same cavities and flow paths. The valve incorporates Sun's floating style construction, which minimizes internal part binding due to excessive installation torque or machining variations in the cavity/cartridge. With a capacity of 7 gpm (28 L/min) and maximum operating pressure of 5000 psi (350 bar), it supports robust performance in hydraulic systems. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) because of fatigue strength limits rather than hydraulic operating limits. The valve features an adjustment mechanism that allows up to five clockwise turns to increase setting, with specific torque requirements for installation and locknut adjustments. It also provides bidirectional flow paths between ports 1 and 2. Weighing .55 lb (.25 kg), this model comes with a Viton seal kit (990021006) for reliable sealing performance 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.
