The Sun Hydraulics DRBPLDN (DRBPLDN) 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 suitable for use as a standalone device or to actuate larger pilot-operated or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 surpasses the preset setting. Notably, port 3 can serve as a work port with bidirectional flow between ports 2 and 3. The direct-acting design ensures low internal leakage and minimal pilot flow consumption, while also allowing interchangeability with pilot-operated versions due to shared cavity and flow path characteristics. This model incorporates Sun's floating style construction to reduce the risk of internal parts binding from excessive installation torque or machining variations. The maximum operating pressure is rated at 5000 psi (350 bar), with a capacity of handling up to 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). The valve is capable of modulating between two positions but is not bistable. Pressure at port 4 directly adds to the valve's setting, while maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. Additional specifications include an adjustment range that requires up to five clockwise turns to increase settings, with installation torque specified between 30 - 35 lbf ft (41 - 47 Nm). Viton seal kits are available for maintenance, ensuring long-term reliability in various applications where precise control over fluid direction is essential.

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.
