Metal Seats Valve Balls


Metal seated ball valves are mainly used for heavy duty applications such as:

High temperatures: above 260 ºC the use of soft seats is not recommended.
Abrassive media: even small particles can damage soft seats.
High Velocity in opening/closing cycles: this action can perfectly deform the soft ring and destroy the seat.

Metal seated ball valves for different services (slurries, pulp and liquors, high temperature, abrasive or sticking fluids, control).

Bubble tight sealing up to 500 ºC
Low coefficient of friction
Excellent sliding and running properties
Hardens the complete surface of ball and seats
