The seat material of general purpose ball valve employs generally non-metal material, such as PTFE, Limited by the seat material, the general purpose ball valve can not be used in case of high temperature application, application medium with solid articles and ash dregs neither, so the applocation scope of general purpose ball valve is restricted partially. Taking this into consideration, our company has developed successfully after years of hard study full range of metal to metal sealed ball valve, including floating ball valve and trunnion ball valve, which have found extensive applications in such industries as petroleum, chemistry, power, metallurgy and light industry.
Forged steel metal to metal sealed trunnion ball valve
Our company's metal to metal sealed trunnion ball valve is in general employing casted steel valve body. As per customers' requirement, forged steel valve body is also available, of which the flange dimensions and face to face dimensions are the same as that of cast steel trunnion ball valve.
Main sizes and weights
Refer to that of floating ball valve for main dimensions and weights of metal to metal sealed floating ball valve. The flange dimensions and face to face dimensions are the same as that of floating ball valve.
