Product Category: gate valve flange 
 Product Name: flange connection manually wedge lined gate valve 
 Product Type: Z41F-25C-DN50 

 Flange connection of the main characteristics and uses of the manual wedge fluorine gate valve: 

 A large diameter valve steel, not easily deformed, the design of the valve channel flow line, flow resistance coefficient. 
 2, the sealing surface of stainless steel or carbide, high hardness and wear-resistant and long service life. 
 3, flexible graphite packing, sealing, reliable, light and flexible operation. 
 Drive the form of break up wheel, gear drive, electric drive; drive way points manually, electric, pneumatic, hydraulic. Structure is divided into elastic Figure a single gate type. 
 5 is widely used in oil, water, steam and corrosive media pipeline for opening and closing device connected to cut off media 

 Flange connection manually wedge the fluorine gate valve valve Overview 

 Flange connection manually wedge lined gate valve strong Germany valve R & D production of the body there are two kinds of flat body and a round body, valve body, valve cover, the gate of the valve stem and other direct contact with the media components, all packings FEP (F46) or PCTFE (F3) and fluorine plastics. Seal pair for the FPE (F46) / FEP (F46) coefficient of friction is small, the opening and closing torque low. Packing with PTFE (F4) standard packing, good sealing performance, easy maintenance and replacement. Flexible gate to compensate for the wedge angle of deviation between the gate seal surface and the valve seat sealing surface, the goodness of fit, seal the results are satisfactory. Media from both sides in any direction through the valve, for the pipeline may change the direction of the medium for opening and closing device. 

 Flange connection manually wedge fluorine gate valve of the highest quality ductile iron or carbon steel casting is made with high strength, light weight, precise geometric dimensions. The gate is interchangeable, the installation of the bodies of spiral bevel gears and effort, can very easily switch can also be opening and closing instructions based on the user's requirements to install columns, or electric, pneumatic implementing agencies. Sealed, rust-proof function good, safe, reliable, long life.
