APPLICATION
VN3 series electricball valves can be used in residential andcommercial buildingsto control theflow ofhot orcold liquids.
Each set includes an electricactuator and a valve body.
Theactuator receives a 0–10V analog signal that controls thevalve opening anda 0–10V feedback signalindicates the opening degree ofthe valve.
The 0–10V control signaladopts incremental control, so when thecontrol signal increases, the valve opening degree increasesaccordingly.
The valve is fully closedat 0V and fully openat 10V.
The VN3 seriesoffer a widerange of screwthread connection standards for different regions, with two-way and three-wayvalve bodiesto cover most
buildingcontrol applications.
