Pressure-Temperature Curves

Data based on clean water media and a 25-year safety lifespan; application in other media requires reduced temperature and pressure.

Flow Capacity

Data at 20°C with clean water media and a 1bar pressure difference;
Cv = Kv X 0.07
Fv = Kv X 0.0585
Kv (liters/min)
Cv (gallons/min) US
Fv (gallons/min) GB

Relative Flow Linearity Graph

The relative flow linearity coefficient refers to the flow variation as a function of valve opening stroke.
