For most applications and up to a temperature of 200 °C we use:
For higher temperatures and/or pressures we can also use other high performance plastics such as:
PEEK PVX, Sintimide,...
Those materials allow permanent temperatures of more than 250 °C and for short time use temperatures of up to 300 °C.
Chemical stability has to be checked in every case.
For abrasive media and/or higher temperatures hardened metal seats are used.
A special procedure known as kolsterising is used in order to abtain the chemical characteristics of the perforated disc.
Varibell® is a rotary quarter turn valve. The regulating element is a bell shaped plug, featuring tear drop shaped apertures machined into both inlet and outlet but laterally reversed. During opening, this plug rotates and simultaneously uncovers the two tear drop apertures giving fine flow adjustment with a 2 stage pressure reduction across both seats.
