Secondary Metal Seats

Triple Offset / Butterfly Valves

The manufacturing process of the secondary metal seat is produced from “Spun“ metal giving a perfectly flat and scratch free surface regardless of diameter, and allows us to achieve a 0.15mm tolerance between the critical radii on which the valve disc seals.

Precision water jet cut and spun metal valve seats are supplied in various metals.
