Product Structure Featuresú
1. Upper flange: standardized driving device flange, conforming to ISO5211
2. Valve body: ductile iron and other applicable materials shall be selected
3. Valve plate: the streamlined valve plate can effectively reduce pressure loss and flow loss. The edge of the valve plate is processed by spherical surface and polished manually. It has the characteristics of small specific operating torque, long service life of the valve seat and good sealing performance. It can be selected according to a variety of media materials. It is connected with the internal transmission of the rotating shaft, with better anti-corrosion performance.
4. Rubber valve seat: Shoe valve seat and integrated valve seat can completely isolate the valve body from the medium. Compared with other structural valves, the valve seat is installed more firmly and has a very low torque value. There is no need to add flange gaskets at both ends during installation. It can be applied to various materials and suitable for the end of the pipeline (lug type).
5. Valve rod: the central line type double half shaft valve rod is designed with flat, square and hexagonal valve plate transmission, two-way sealing, no leakage, and no flow restriction during installation.
7. “O” ring: NBR butyl rubber, effective dust prevention and internal leakage prevention.
8. ‘U’ type lock plate and circlip can effectively prevent the shaft from blowing out.
