D71F-16 tetrafluoride handle wafer butterfly Profile: PTFE valve is to meet some of the need to have more specific areas of acid, alkali corrosive environment, petroleum, chemical, food, etc., using Teflon valves body, has a strong anti-corrosion effect. Under normal conditions can replace stainless steel body, with a higher price. Butterfly butterfly plate installed on the pipe diameter direction. Cylindrical channel in the valve body, disc-shaped disc around the axis of rotation, rotation angle between 0 ° ~ 90 °, rotated to 90 °, the valves are open all license conditions. AKR tetrafluoride can be equipped with electric butterfly valve, BY pneumatic actuators, input control signal (4 ~ 20mADC or 1 ~ 5VDC) and single-phase power to control the operation, enabling intelligent (modulating) and switch type. Functional, small volume, light and pleasant, reliable performance, supporting simple, 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 in many fields of petroleum, chemical, metallurgy, water, electricity and very widely used. Has been known butterfly technique, seal forms enclosed structure, sealing material for rubber, PTFE and so on. Due to restrictions structural characteristics, suitable for high temperature, high pressure and corrosion resistance, abrasion resistance and other industries. Scope: Suitable for water supply and drainage, power generation, oil, gas (natural gas), chemical, metallurgy, food (beverages), pharmaceutical, paper, shipbuilding, environmental protection and other engineering systems transport all kinds of corrosive and non-corrosive fluid medium pipe on the road and the container, and to cut off the flow regulating medium. Tetrafluoroethylene butterfly Features: 1, simple and compact structure, light weight, ease of assembly and disassembly and repair. 2, the operating torque is small, turn 90 ° opening and closing the light quickly. 3, flow resistance, flow characteristics approximate linear tilt, energy-saving effect. 4, reliable sealing, zero leakage, long service life. 5, can be made of various materials, for a variety of media.
