The Sun Hydraulics DRBPKAN (DRBPKAN) is a direct-acting, 3-way directional cartridge valve designed for use in moderate flow circuits. This component serves as a switching device with a configuration that allows flow from port 1 to port 2 while keeping port 3 blocked. It can function independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold, and it features bidirectional flow paths between ports 1 and 2 as well as ports 2 and 3. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits. The DRBPKAN incorporates Sun's floating style construction, which helps minimize the risk of internal parts binding due to excessive installation torque or machining variations. It fits into T21A cavities and offers a capacity of up to 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). The valve is not bistable but can modulate between two positions, ensuring precise control within hydraulic systems. Additional specifications include a valve hex size of .78 inches (22.2 mm) and an installation torque requirement of between 30-35 lbf ft (41-47 Nm). The adjustment screw has an internal hex size of .532 inches (4 mm), with the locknut requiring a torque of between 80-90 lbf in (9-10 Nm). The model weighs .55 lb (.25 kg) and is compatible with Viton seal kits, specifically part number 990021006.

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.
