3E Engineering manufactures in general trunnion ball valve of casting steel and stainless steel body,however,if required by customers,forged carbon steel and stainless steel and others special.
forged materials are available,of which the flange dimensions and face to face dimensions are the same as that of casting trunnion ball valves.
Except for full bore ball valves,3E Engineering also supply ball valves with reduced bore to meet different of customers requirements,which not only lowers the cost and pricing,but also satisfies the special requirement of customers.
