Seal Material:
EPDM
EPDM rubber represents ethylene propylene diene monomer, and
because EPDM has excellent heat resistance, its solenoid valve
seals are recommended for use over NBR temperature ranges such as
hot water and low pressure steam. The maximum service temperature
of EPDM is about 120 c, and it has good tolerance to acid, base and
salt.
VITON
VITON (FKM) is the brand name for the synthetic rubber and
fluoropolymer elastomers in DuPont. It is usually used for o-rings
and other molded or extruded products. They can be used in
automobile and petroleum exploration applications because of their
excellent heat resistance, which can make the working temperature
close to 150 degrees Celsius.
