The Sun Hydraulics DRBPLWN (DRBPLWN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the preset threshold. Port 3 serves as a work port, with bidirectional flow paths between ports 2 and 3, as well as between ports 1 and 2. The valve's design minimizes internal leakage and pilot flow consumption due to its direct-acting nature, and it is interchangeable with pilot-operated versions within the same cavity. The DRBPLWN incorporates Sun's floating style construction to reduce the likelihood of internal component binding from excessive installation torque or machining variations in the cavity/cartridge. It features a maximum operating pressure of 5000 psi (350 bar) and a capacity of up to 7 gpm (28 L/min), 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 considerations. Installation specifics 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 valve weight is approximately .55 lb (.25 kg), and it utilizes Viton seal kits for cartridge sealing. This model is not bistable but can modulate between two positions, making it suitable for various applications where precise control over fluid direction is required.

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.
