The Sun Hydraulics DRBNCSV (DRBNCSV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It is versatile in its applications, serving as a standalone device or in conjunction with larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds its set value. Notably, port 3 can be utilized as a work port, and the flow path between ports 2 and 3 is bidirectional. Thanks to its direct-acting design, the DRBNCSV offers low internal leakage and minimal pilot flow consumption. Both direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities with identical flow paths. The valve incorporates Sun's floating style construction to reduce the risk of internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. It features a cavity type T21A and belongs to Series 1 with a capacity of 7 gpm (28 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). The valve allows for adjustment through clockwise turns to increase settings, featuring specific hex sizes for both the valve and adjustment screw. The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. With a model weight of .55 lb (.25 kg), this valve includes Viton seal kits for enhanced durability. Additionally, it features a maximum valve leakage rate of 2 in\u00b3/min (30 cc/min) at an oil viscosity of 110 SUS (24 cSt), ensuring efficient operation within specified parameters.

Normally closed, direct-acting, 2-way directional cartridges 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.
- 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.
