Solenoid valve operating temperature of various media

The media temperatures for different valve body and bonnet materials are as follows:

Suitable for medium for malleable cast iron body and bonnets up to 300 °C.

Ductile iron body and bonnet are suitable for media up to 350 °C.

The high silicon cast iron body and bonnet are suitable for media up to 120 °C.

When the valve lining is made of rubber or plastic, the temperature resistance of rubber and plastic shall prevail.

Ceramic and glass valves, which have poor temperature and temperature resistance, are generally used below 90 °C.

The temperature resistance of enamel valves is limited by the material of the seal, exceeding 150 °C at the highest medium temperature.

The medium used for gray cast iron body and bonnet is up to 250 °C.

Carbon steel body and bonnet are suitable for media up to 425 ° C (forging 16 Mn, 30 Mn up to 450 ° C).

Cr5Mo alloy steel body and bonnet are suitable for media up to 1550 °C.

1Cr18Ni9Ti and Cr18Ni12Mo2Ti stainless steel body and bonnet are suitable for media up to 600 °C.

Copper alloy valve bodies and bonnets are suitable for media up to 200 °C.

Titanium body and bonnet are suitable for media up to 300 °C.

Medium for plastic valve body and bonnet Maximum use temperature: nylon 100 ° C, chlorinated polyether 100 ° C, polyvinyl chloride 60 ° C, polychlorotrifluoroethylene -60 ~ 120 ° C, polytetrafluoroethylene - 180 ~ 150 ° C .

Rubber diaphragm valves depend on the type of rubber, natural rubber 60 ° C; nitrile rubber, neoprene 80 ° C; fluoro rubber 150 ° C.
