Select Code Based on Requirements
Pressure-Temperature Curves
Data based on clean water media and a 25-year safety life; applications with other media must reduce temperature and pressure.
Flow Capacity
Data based on 20°C clean water media and a 1 bar pressure difference;
Cv = Kv X 0.07
Fv = Kv X 0.0585
