Fully welded flanged ball valves

Product Overview

Fully welded flange ball valve is a very good energy-saving and environmental protection products, its characteristics when the valve is off internal leakage can reach the state of "zero leakage", can make the loss caused by energy loss to the lowest point.Greatly improves the accuracy of energy saving and heat metering.Valves consist of an all-welded body and carbon-reinforced Teflon gasket for frequent operation and long life in the presence of impurities and chemicals.The finely ground stainless steel ball can be opened and closed freely for many years with reliable operation.Products are widely used in natural gas, petroleum, heating, chemical and thermoelectric pipe network and other long - distance pipeline fields, as open and close control devices.Compared with the same specifications in the same industry, the valve body is small and beautiful in appearance.
