The Sun Hydraulics DRBPKAV (DRBPKAV) 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 versatile for use either 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 predetermined setting, with the flow path between ports 2 and 3 being bidirectional. This model is characterized by its low internal leakage and minimal pilot flow consumption due to its direct-acting design. It shares cavity compatibility with pilot-operated versions, allowing interchangeability without altering flow paths. The DRBPKAV can modulate between two positions but is not bistable. It supports a maximum operating pressure of up to 5000 psi (350 bar) and has a capacity of handling flows up to 7 gpm (28 L/min). Additionally, it incorporates Sun\u2019s floating style construction to mitigate the risk of internal parts binding from excessive installation torque or machining variations. The valve\u2019s installation requires specific torque settings, with a valve hex size of 7/8 in (22.2 mm) and an adjustment screw internal hex size of 5/32 in (4 mm). The model weighs approximately .55 lb (0.25 kg) and includes 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.
