The Sun Hydraulics DRBPKBV (DRBPKBV) is a direct-acting, 3-way directional cartridge valve designed to manage moderate flow circuits. It operates by shifting when the pressure differential between port 1 and port 4 exceeds the set threshold. This valve is versatile, allowing for use as a standalone unit or in conjunction with larger pilot-operated directional or logic cartridges. The DRBPKBV features low internal leakage and minimal pilot flow consumption due to its direct-acting design. It offers bidirectional flow paths between ports 1 and 2, as well as ports 2 and 3, with port 3 also serving as a work port. While not bistable, this valve can modulate between two positions based on system demands. The DRBPKBV is built with Sun's floating style construction to reduce the risk of internal binding from excessive installation torque or machining variations. It fits into cavity T-21A and belongs to series 1, with a capacity of handling up to 7 gallons per minute (28 liters per minute). The factory pressure settings are established at a flow rate of 4 gallons per minute (15 liters per minute), supporting a maximum operating pressure of 5000 psi (350 bar). The valve's maximum leakage is rated at 2 cubic inches per minute (30 cubic centimeters per minute) at an oil viscosity of 110 SUS (24 cSt). Additional specifications include an adjustment range that requires approximately five full clockwise turns to increase settings, a valve hex size of .78 inches (22.2 mm), and an installation torque ranging from 30 to 35 lbf-ft (41 to 47 Nm). The locknut hex size is .916 inches (15 mm) with a torque requirement of 80 to 90 lbf-in (9 to 10 Nm). The model weighs approximately .55 pounds (.25 kg) and uses Viton seal kits for optimal performance.

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.
