Ball valve is a type of shut-off valve in which the moving part of the gate has the form of a ball with a hole for the flow of media. Ball valve is quite simple in operation and reliable in operation. The main application of such a valve is the passage of liquid, gas or steam. Ball valves are made of such materials as cast iron, brass, copper, steel and polypropylene. WING ball valve is a ball valve with transitions to the crimped connection to connect to the metal polymer pipes, as well as pipes made of cross-linked polyethylene.
It is used with metal-plastic pipes in heating and water supply. Pipeline fittings, which are used to connect the metal-plastic pipes are made of very high quality brass, so they withstand pressure of more than 20 atmospheres, and to prevent oxidation the fitting is coated with nickel. The use of ball valves as control valves is not allowed.
