Seat with O-ring.

The O-Ring seat consists of two rings including an O-Ring made of elastomeric material and a metallic elastic ring lock seat

Mostly this kind of seat is produced with carbon steels and then nickel plated but sometimes also with stainless steels. The elastomeric sealing gasket has a hardness of 98SH and AED condition.

This type of seat assembly is successfully used in low series valves (up to 900 series) when fluid, temperature and other conditions permit it.
