Flange fluorine turbine butterfly valve
Apart from the butterfly valve in the pipeline and the closure by cutting, in recent years has been the sealing performance as the main evaluation index, favored by the market. In addition, the butterfly still has the advantages of small size, light weight and simple structure advantages, compared with the same parameters valve, the average weight of 30-50%, the butterfly plate rotating 90 degrees can be realized the opening and closing process, because the media is approximately equal to the force, shaft on both sides of the disc by the torque on the contrary, the smaller opening and closing torque.

One, the company introduced the fluorine plastic lined butterfly valve series
There are two kinds of 1 basic types, namely D71F4 and D71F46 (middle) and D71F4 and D71F46 (eccentric) full lining butterfly clip on type two, using the bisection valve combination, the valve seat and valve liner valve work, integration, only full plastic seat and lining plastic disc contact with the media, the product can withstand "in addition to any corrosion of molten alkali and fluorine elements", which is also D71F4 stem disc (forging) as a whole, the surface evenly coated with a layer of FEP. in the channel of the valve body surface smooth, fluid resistance, high CV value, strong circulation, moderate torque, the four seal structure and the seal surface. With high temperature aging elastic rubber gasket seat SI, zero leakage of the medium.
2 the above model is extended to the D71F and D41F type flange connection valve full lining, butterfly plate for stainless steel lined butterfly valve.
3.D343F type flange connection double eccentric full lining butterfly valve.
