Product description

       The all-welded flanged ball valve is a very good energy-saving and environmentally-friendly product. Its characteristic is that when the valve is closed, the internal leakage can reach a "zero leakage" state, which can reduce the loss caused by energy loss to the lowest point. Greatly improve the accuracy of energy saving and thermal energy measurement. The valve is composed of a fully welded valve body and a carbon-reinforced Teflon gasket, which can be operated frequently and has a long life in the presence of impurities and chemical substances. The finely ground stainless steel sphere can ensure that it can be opened and closed freely for many years, and the operation is reliable. The products are widely used in the fields of long-distance pipelines such as natural gas, petroleum, heating, chemical and thermal power pipeline networks, as the control device for opening and closing. Compared with products of the same specification in similar industries, the valve body is small and beautiful in appearance.

Scope of application

       City gas: gas output pipeline, main line and various branch supply pipelines, etc. Centralized heating: output pipelines, main lines, and branch lines of large-scale heating equipment. Heat exchanger: the pipeline and each circuit are opened and closed. Iron and steel plants: various fluid pipelines, exhaust gas discharge channels, gas and heat supply pipelines, fuel supply pipelines, etc. All kinds of industrial equipment: all kinds of heat treatment pipelines, all kinds of industrial gas and heating pipelines.

Product Features
