BN1101F series plastic-lined butterfly valves have both the temperature resistance of hard liner and the sealing characteristics of soft liner. When the valve works, only the perfluorinated plastic valve seat and the fluorine-lined butterfly plate are in contact with the medium.
Product Description
BN1 series plastic lined butterfly valve is a structure designed with three-dimensional eccentric principle, soft seal, soft and hard multi-level seal and full metal seal processing technology, so that the plastic lined butterfly valve in operation work, reduce its torque force, to achieve the function of labor saving and energy saving. Plastic lined butterfly valve not only can resist the severe working conditions of high temperature and pressure, but also has excellent sealing performance, hard seal valve seat sealing surface, overlay welding cobalt-based hard alloy, wear resistance, long service life.
Wide Size & Pressure Range
Available in DN15 to DN1000, covering a broad spectrum of piping requirements.
