The Sun Hydraulics DRBNLAV (DRBNLAV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device and can be utilized independently or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve activates when the pressure differential between port 1 and port 4 surpasses the predetermined setting. Port 3 serves as a work port, with a bidirectional flow path between ports 2 and 3. Thanks to their direct-acting design, these cartridges offer low internal leakage and minimal pilot flow consumption. Direct-acting and pilot-operated versions of these valves are interchangeable, sharing the same cavities and flow paths. Pressure at port 4 directly adds to the valve setting, allowing modulation between two positions rather than bistability. The maximum pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. Sun's floating style construction is incorporated to minimize internal part binding due to excessive installation torque or cavity/cartridge machining variations. This valve fits into cavity T21A with a series capacity of up to 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). Maximum valve leakage at 110 SUS (24 cSt) is rated at 2 in\u00b3/min (30 cc/min). Adjustment involves up to five clockwise turns to increase the setting, with specific hex size requirements for installation torque and adjustment screw manipulation. The model weighs approximately .55 lb (.25 kg) and includes Viton seal kit option number 990021006 for cartridge sealing needs.

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.
