BUTTERFLY VALVES WITH ELASTOMER SEAT - Size: from 1 ½ '' to 48'' - Rating: ANSI 150 - Types of end connection: wafer and lug; - Materials: grey iron, carbon steel, stainless steel, (other materials upon request); - Applications: iron and steel, ship building, textile, chemical and petrochemical industries,   water treatment processes and dyeing plants, air conditioning and heating sector. The compaction and lightness represent other advantages of these valves, reducing the weight and the dimensions they can easily be installed in small spaces. The seal performances are improved thanks to the elastomer seat with reinforcement that ensures a geometric stability. The elastomer seat can be easily changed thanks to its particular design. The elastomer seat isolates the body from the fluid allowing the choice of a less expensive material and for its design it allow a simple installation of the valve directly on the piping.
