Stafsjö introduce FEPM seat for high temp and chemical services
We are proud to announce the arrival of our new rubber valve seat compound FEPM to WB11, WB14 and specifically to the full stainless steel high performance WB14E. Initially we released it for DN 80/3” – DN 300/12” except for DN 125/5”. After thorough testing we release it up to DN 600/24″.
The FEPM seat material has excellent resistance to wide range of aggressive chemicals, both acids and bases, and steam at high continuous service temperatures within -10 °C/14 °F up to 180°C/356 °F including short term peeks up to + 225 °C/437 °F. The compression set resistance at these high temperatures is superior to other standard rubber materials, but it is limited in low temperature applications. Function tests shows that the FEPM material can give the sealing system considerably longer life time compared to standard rubber compounds. This makes the FEPM seat suitable for severe applications where you need a long-lasting performance and a tight shut-off.
