STV-K PEEK & STV-R PPS Molded Isolation Valves
Solenoid Operated, Two way & Three way Valves
DESCRIPTION
Model STV-K or STV-R isolation valves have molded PEEK or PPS valve bodies and PTFE isolation diaphragm materials for compatibility with aggressive media. The valves are standard with unique Perfluor soft elastomeric seals which are forgiving of particulate matter that would typically damage a plastic valve seat.
The STV-K and STV-R valves are excellent choices for demanding low flow applications where minimum size and internal volume are requirements.
