The Sun Hydraulics DRBNLWV (DRBNLWV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for use in moderate flow circuits. This versatile component functions either independently or as an actuator for larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses its set threshold, with port 3 available as a work port. The bidirectional flow path between ports 2 and 3 ensures flexibility in various applications. Notably, this valve's direct-acting design results in low internal leakage and minimal pilot flow consumption. The DRBNLWV is interchangeable with pilot-operated versions, sharing the same cavity fitment and flow paths. It features Sun's floating style construction to reduce the risk of internal binding due to installation torque or machining variations. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min), this cartridge is robust yet efficient. Factory pressure settings are established at 4 gpm (15 L/min), ensuring optimal performance under specified conditions. The valve is adjustable with up to 5.5 clockwise turns to increase settings, and it incorporates a locknut for secure adjustments. The maximum allowable pressure at port 3 is capped at 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating constraints, ensuring durability under prolonged use. This model also includes a Viton seal kit for enhanced reliability in various environments. Overall, the Sun Hydraulics DRBNLWV is an efficient solution for applications requiring reliable switching devices in hydraulic systems, offering precise control and adaptability across diverse operational demands.

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.
