Forged steel valve cover to connect the three body design of the form There are three forged steel valve cover to connect the body design of the form: The first is the body of forged steel globe valve bolted cover, designed by the connection form of the valve, the valve body and valve cover bolt connection, spiral wound gasket seal, the advantage of easy maintenance. The second body of solder connections forged steel valve cover, according to the design of this connection in the form of valve, the valve body and seal welded bonnet, the advantage of no external leakage. The third is the pressure from the tight bonnet forged steel globe valve, according to the design of this connection in the form of valve, the valve body and bonnet connection with screw mosquito, pressure from the seal ring seal, the greater the advantage of internal pressure, the sealing performance, the better. You can be reasonably based on the actual valve.
