The Sun Hydraulics DRBPLEN (DRBPLEN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits, providing reliable switching functionality. This model features a configuration where ports 1 and 2 are open while port 3 is blocked, allowing it to be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve actuates when the pressure differential between port 1 and port 4 exceeds its set threshold. Notably, port 3 can function as a work port, with bidirectional flow capability between ports 2 and 3. The direct-acting design ensures low internal leakage and minimal pilot flow consumption, enhancing efficiency. This valve can modulate between two positions rather than being bistable, offering flexibility in operation. It incorporates Sun's floating style construction to reduce the risk of internal parts binding due to installation torque or machining variations. The DRBPLEN has a maximum operating pressure of 5000 psi (350 bar) and should limit pressure at port 3 to 3000 psi (210 bar) due to fatigue strength considerations. The valve fits into cavity T-21A and belongs to series 1 with 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 an installation torque requirement of 30 - 35 lbf ft (41 - 47 Nm), the valve's design ensures secure placement and reliable performance. Additionally, it boasts an adjustment screw with an internal hex size of \\(\\frac{5}{32}\\) inches (4 mm), allowing for precise calibration with up to five clockwise turns needed to increase settings. Featuring Viton seals for durability under various conditions, this cartridge valve weighs approximately .55 lb (.25 kg).

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.
