The Sun Hydraulics DRBNKBV (Material Number: DRBNKBV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It is versatile in application, functioning independently or as an actuator for larger pilot-operated or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds its set value. Port 3 serves as an optional work port with bidirectional flow capability between ports 2 and 3. This direct-acting valve boasts low internal leakage and minimal pilot flow consumption, making it efficient in performance. Both direct-acting and pilot-operated versions are interchangeable, sharing the same cavity and flow paths. The DRBNKBV model features a maximum operating pressure of 5000 psi (350 bar) and is constructed with Sun's floating style to minimize internal binding risks due to installation torque or machining variations. The valve capacity stands at 7 gpm (28 L/min), with factory pressure settings established at a flow rate of 4 gpm (15 L/min). Maximum valve leakage is limited to 2 in\u00b3/min (30 cc/min) at a viscosity of 110 SUS (24 cSt). The design includes an adjustable screw for setting modifications, requiring up to five clockwise turns to increase the setting. Installation specifics include a valve hex size of 7/8 inch (22.2 mm) with an installation torque range of 30-35 lbf ft (41-47 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), while the locknut hex size measures at 9/16 inch (15 mm), necessitating a torque range of 80-90 lbf in (9-10 Nm). The model weighs approximately .55 lb (.25 kg) and utilizes Viton seal kits for reliable sealing performance under various conditions.

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.
