The Sun Hydraulics DRBPKWN (DRBPKWN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It is typically used as a switching device, either independently or to actuate larger pilot-operated directional or logic cartridges. This valve shifts when the pressure differential between port 1 and port 4 exceeds the set threshold. It features bidirectional flow paths between ports 1 and 2, as well as ports 2 and 3, with port 3 also serving as a work port. The design ensures low internal leakage and minimal pilot flow consumption, thanks to its direct-acting nature. The DRBPKWN valve can modulate between two positions but is not bistable, making it versatile for various applications. The cartridge fits into a T21A cavity and belongs to Series 1 with a capacity of up to 7 gpm (28 L/min). It operates at a maximum pressure of 5000 psi (350 bar) with factory pressure settings 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 limits. This model incorporates Sun's floating style construction to prevent internal part binding from excessive installation torque or machining variations in the cavity/cartridge. Additional specifications include a valve hex size of .78 inches (22.2 mm), an installation torque range of 30-35 lbf ft (41-47 Nm), and an adjustment screw internal hex size of .532 inches (4 mm). The locknut hex size is .916 inches (15 mm), with a torque requirement of 80-90 lbf in (9-10 Nm). Weighing .55 lb (.25 kg), the DRBPKWN model also comes with a Viton seal kit for reliable sealing 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.
