The extremely compact proportional valve type 2861 is available up to a nominal diameter of 2mm and is based on the higher standard version of type 2871. It serves as an actuator in closed process control circuits (pressure, flow, temperature, etc.).
Compared to the standard version, the valve essentially has a simpler interior design, and installation and testing effort are optimized so that higher batch sizes can be operated for large-volume applications in a shorter time.
The kv factor indicates the volume flow through a valve, measured in litres/min at 1 bar and at a water temperature between 5 and 30°C. The QNn factor indicates the gas volume flow, measured in litres/min
