Teflon lined diaphragm valve manufacturer, factory and supplier in China. G41F46-10 Teflon lined diaphragm valve is a special form of valve with truncation function, G41F46-10 Teflon lined diaphragm valve is a truncation valve. Its opening and closing part is a diaphragm made of soft material, the diaphragm valve body cavity and the valve cover cavity and drive parts separated, so called diaphragm valve. G41F46-10 Teflon lined diaphragm valveis composed of a diaphragm made of steel valve disc and soft material (rubber and fluorine plastic composite), and the valve body cavity and the cover cavity is separated to achieve the purpose of truncating the medium in the tube. G41F46-10 Teflon lined diaphragm valve is widely used in the production system of chemical, acid, alkali, smelting, rare earth, pesticide and other industries. 

G41F46-10 Teflon lined diaphragm valve features:

 1. The difference between G41F46-10 Teflon lined diaphragm valve and other valves is that: the structure of no packing box; G41F46 fluorine lined diaphragm valve diaphragm can make the corrosive medium in the flow channel and all the driving components in a completely isolated state, so as to eliminate the usual valve "run, take, drop, leakage" and other drawbacks.
2. Due to the smooth flow path of the diaphragm valve, the flow resistance is small, so the larger flow rate can be obtained.
3. The body cavity of G41F46-10 Teflon lined diaphragm valve is lined with PTFE PFA FEP. Therefore, it has superior corrosion resistance.
4. Because the sealing parts are elastic tetrafluorodiaphragm. Therefore, it also has better sealing and closing force.
5. G41F46-10 Teflon lined diaphragm valve is composed of valve body, valve cover, disc, stem, diaphragm and other driving parts.
6. The opening and closing of PFA FEP PFA lined diaphragm valve are achieved by rotating the hand wheel. The valve is marked on the upper end of the valve cover with visible valve opening or closing position display color, to indicate the valve opening and closing stroke. When the hand wheel is placed clockwise, the hand wheel moves down, and the disc drives the diaphragm down to cut off the path; On the contrary, the valve is opened and the color is revealed.
7. G41F46-10 Teflon lined diaphragm valve adopts standard: in accordance with the provisions of GB12239, and in accordance with BS5156.
8. Non-toxic: with physiological inertia, can be used for food sanitation pipeline.
9.No leakage: Body packing design prevents fluid from leaking at stem.
10.Remote control can be realized by adding pneumatic actuator.
