Metal Seated Ball Valve
Product Features
High Tempreture Service
General soft seated ball valve can be worked no more than 300℃, but metal
seated ball valves can reach 400℃.
Low
Pressure Reliable Sealing
Our metal to metal ball valve adopt seat spring structure, which
can push upstream seat tightly agains the ball surface creating a reliable even
if extreamely low pressure.
Valve
Stuck Under High Temperature Prevented
In the case of high temperature working condition, the valve seat and ball
would easily get stuck due to heat expansion, and the valve could not be open.
Metal to metal seated ball valves employ the design of bevelling spring
loading,which would absorb the heat expansion of parts caused by the bevelling
spring. So, it is ensured that the valve would not get stuck and be open and
close easily in the case of high temperature condition
