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.
Structural Characteristics
- Easy to install without maintenance, adjustment and lubrication.
- It can be operated frequently and run for a long life in the presence of impurities and chemicals.
- The stem can be lengthened, easy to heat preservation;
- The operating handle can be removed for reversing installation;
- Body does not contain heavy and unreliable castings.
