The Sun Hydraulics DRBNLSV (DRBNLSV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can operate independently or be used to actuate larger pilot-operated directional or logic cartridges. Its operation is triggered when the pressure differential between port 1 and port 4 surpasses the preset level. The valve features a bidirectional flow path between port 2 and port 3, with port 3 also serving as a work port. Due to its direct-acting design, it boasts low internal leakage and minimal pilot flow consumption. The DRBNLSV is interchangeable with pilot-operated versions, fitting the same cavities and sharing similar flow paths. Pressure at port 4 directly influences the valve setting, while maximum pressure at port 3 should not exceed 3000 psi due to fatigue strength constraints. The Sun floating style construction minimizes risks of internal part binding caused by excessive installation torque or machining variations in cavity-cartridge interfaces. The valve fits into cavity T21A, belongs to series 1, and has a capacity of up to 7 gpm (28 L/min). It operates effectively at a maximum pressure of 5000 psi (350 bar) with factory pressure settings calibrated at 4 gpm (15 L/min). The DRBNLSV's adjustment features include an increase setting through clockwise turns (up to five) with specific torque requirements for installation and locknut adjustments. It weighs approximately .55 lb (.25 kg) and is equipped with Viton seal kits for enhanced durability. This cartridge valve is optimal for applications requiring fast response times, stability under varying conditions, and robust performance in hydraulic systems where precise control over fluid direction is essential.

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.
