PTFE Lined Gate Valve

ADVANTAGES

Product Identification：

Fluorine lined gate valve adopts fluorine plastic lining layer, which has extremely high chemical stability and is suitable for chemical medium;
Fluorine lined gate valve is professionally designed to control all kinds of strongly corrosive media. Fluorine Lined gate valve is widely used in petroleum, chemical, dyeing, pesticide, acid and alkali production, ect. It is currently the good choice of anti-corrosion valve.

Advantage:

1. Adopting precision casting process, the material performance of the valve body meets the national standards;
2. The valve body adopts the structure suitable for lining process requirements, and the valve body and inner parts in direct contact with the medium are all lined with fluorine plastic;
3.The seal is FEP/FEP or other material combination, small friction coefficient, low opening and closing moment;
4. PTFE packing has good sealing performance, easy maintenance and replacement;
5. Elastic gate wedge can compensate the sealing surface deviation, with good sealing effect and zero leakage
