Ventilation Butterfly Valve is generally based on its operating pressure and temperature classification: 
High pressure valve, nominal pressure TB> 100MPa butterfly. 
High pressure butterfly valve, nominal pressure TB is 100 - 80.0MPa butterfly. 
Medium pressure valve, nominal pressureTB is 2.5 - 6.4MPa butterfly. 
Low-pressure valve, nominal pressure TB <1.6MPa butterfly. 
Vacuum valve working pressure lower than atmospheric calendar marked heap butterfly. 
If classified according to operating temperature, namely: 
High temperature butterfly valves. t> 450 ℃ of butterfly 
The temperature butterfly valve. 120C <t <450C valve 
Temperature butterfly valves. - 40C <t <120C valve 
Cryogenic butterfly valves. - 100 <t <- 40C butterfly 
e cryogenic butterfly valves. t <- 100C Butterfly
