Tetrafluoroethylene butterfly is to meet some of the need to have more specific areas of acid, alkali corrosive environment, petroleum, chemical, food, etc., the use of the body made of polytetrafluoroethylene, has a strong antiseptic effect. Under conventional conditions can replace stainless steel body, with a higher price. Butterfly valve plate is mounted on the pipe diameter direction. Cylindrical channel in the valve body, disc-shaped disc around the axis of rotation, rotation angle between 0 ° ~ 90 °, the rotation to 90 °, the valve is open all license conditions. Tetrafluoroethylene valve can be equipped with electric AKR, BY pneumatic actuators, input control signal (4 ~ 20mADC or 1 ~ 5VDC) and single-phase power to control the operation, enabling intelligent (Smart) and switch type. It has a strong functions, small, light and pleasant, reliable, simple matching, flow capacity, especially suitable for viscous media containing particles, fibers nature of the occasion. Currently, PTFE butterfly as a piping system used to implement off and flow control components, has been used in many fields of petroleum, chemical, metallurgy, water, electricity and very widely used. It has been known butterfly valve technology, the seal forms enclosed structure, sealing material for rubber, PTFE and so on. Since the structure of the restrictions, suitable for high temperature, high pressure and corrosion resistance, abrasion resistance and other industries. Scope: apply to water supply and drainage, power generation, oil, gas (natural gas), chemical industry, metallurgy, food (beverages), pharmaceutical, paper, shipbuilding, environmental protection and other engineering systems transport all kinds of corrosive, non-corrosive fluid medium pipe on the road and container for regulation and cut off the flow of the medium. Features tetrafluoroethylene valve Features: 1, simple and compact, lightweight, easy assembly and disassembly and repair. 2, the operating torque is small, light open and close rapidly turn 90 °. 3, flow resistance, flow characteristics inclined linear approximation, energy-saving effect. 4, reliable sealing, no leakage and long service life. 5, can be made of various materials, for a variety of media.
