The Sun Hydraulics DRBPLDV (DRBPLDV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It functions by opening the flow path between ports 1 and 2 while blocking port 3, shifting when the pressure differential between ports 1 and 4 exceeds the set threshold. This valve is versatile, serving as a standalone unit or actuating larger pilot-operated directional or logic cartridges. Notably, it features bidirectional flow paths between ports 1 and 2, as well as ports 2 and 3. The valve's direct-acting design ensures low internal leakage and minimal pilot flow consumption. It can modulate between two positions but is not bistable. The DRBPLDV is interchangeable with pilot-operated versions, fitting the same cavities and maintaining identical flow paths. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of up to 7 gpm (28 L/min), this valve incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. The valve includes specific adjustment features such as a hex size of \\( \\frac{7}{8} \\) inch (22.2 mm), requiring an installation torque of 30-35 lbf ft (41-47 Nm). Additionally, it has an adjustment screw internal hex size of \\( \\frac{5}{32} \\) inch (4 mm), with a locknut hex size of \\( \\frac{9}{16} \\) inch (15 mm), requiring a locknut torque of 80-90 lbf in (9-10 Nm). This model weighs approximately .55 lb (.25 kg) and utilizes Viton seal kits for optimal performance in various applications.

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.
