The Sun Hydraulics DRBNLBV (DRBNLBV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds the set threshold. Port 3 serves 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, making it efficient for various applications. These valves are interchangeable with pilot-operated versions, sharing the same cavities and flow paths. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits, although the operating limit is higher at 5000 psi (350 bar). The DRBNLBV features Sun's floating style construction, minimizing risks of internal part binding from excessive installation torque or machining variations in cavity-cartridge setups. It fits into a T-21A cavity and has a capacity of up to 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). The valve allows for adjustments through clockwise turns to increase settings, with specific torque requirements for installation and locknut adjustments. This model weighs .55 lb (.25 kg) and uses Viton seal kits for maintenance. Overall, its robust construction and reliable performance make it suitable for applications requiring precise modulation between two positions without bistability concerns.

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.
