The Sun Hydraulics DRBNLAN (DRBNLAN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can operate independently or in conjunction with larger pilot-operated directional cartridges or logic cartridges. It activates when the pressure differential between port 1 and port 4 surpasses the preset level. Port 3 serves as a work port, with a bidirectional flow path between ports 2 and 3. Due to its direct-acting design, the DRBNLAN features low internal leakage and minimal pilot flow consumption. Direct-acting and pilot-operated versions are interchangeable, fitting the same cavities with identical flow paths. The pressure at port 4 directly adds to the valve's setting. This non-bistable valve can modulate between two positions as shown in its specifications. The DRBNLAN is constructed using Sun's floating style design to reduce internal part binding risks caused by excessive installation torque or cavity-cartridge machining variations. It fits into cavity T21A of series 1 and has a capacity of handling up to 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), while maximum valve leakage is limited to 2 in\u00b3/min (30 cc/min) at viscosity levels of 110 SUS (24 cSt). For adjustments, there are up to five clockwise turns available for increasing settings, with specific torque requirements for installation and locknut adjustments provided in its technical data. The model weighs approximately .55 lb (.25 kg) and comes with a Viton seal kit option under part number 990021006.

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.
