What is the suitable medium temperature for different body and cover materials?
The suitable medium temperatures for different body and cover materials are as follows:
The maximum service temperature of medium suitable for grey cast iron valve body and cover is 250 C.
Malleable cast iron valve body and cover are suitable for medium with a maximum service temperature of 300 C.
Ductile iron valve body and cover are suitable for medium with a maximum service temperature of 350 C.
High silicon cast iron valve body and cover are suitable for medium with a maximum service temperature of 120 C.
Carbon steel valve body and cover are suitable for medium with a maximum service temperature of 425 C (forgings 16Mn and 30Mn can reach 450 C).
Cr5Mo alloy steel valve body and cover are suitable for medium with a maximum service temperature of 550 C.
1Cr18Ni9Ti and Cr18Ni12Mo2Ti stainless steel body and cover are suitable for medium with a maximum service temperature of 600 C.
Copper alloy valve body and cover are suitable for medium with a maximum service temperature of 200 C.
Titanium body and cover are suitable for medium with a maximum service temperature of 300 C.
Plastic valve body and valve cover are suitable for medium maximum service temperature: nylon 100 C, chlorinated polyether 100 C, polyvinyl chloride 60 C, polytrifluorochloroethylene – 60 – 120 C, polytetrafluoroethylene – 180 – 150 C.
Rubber diaphragm valves depend on the type of rubber, natural rubber 60 NBR, chloroprene rubber 80 and fluororubber 150.
When using rubber and plastics for valve lining, the temperature resistance of rubber and plastics shall prevail.
Ceramic and glass valves, which have poor temperature resistance and rapid change, are generally used below 90 C.
The temperature resistance of enamel valves is limited by the sealing ring material, and the highest medium temperature is over 150 C .
