Hard sealed butterfly valve

Fluorine lined lug butterfly valve - PFA/PTFE/FEP lined lug butterfly valve is divided into handle drive, worm gear drive, pneumatic and electric; The valve body is divided into two types: fully lined and semi lined. Full lining refers to the valve seat and valve plate being fully lined with tetrafluoroethylene materials such as PFA/PTFE/FEP. Half lined refers to the valve plate not lined and made of materials such as stainless steel SUS304 or SUS316

2/Two piece lined lug butterfly valve. The lug butterfly valve adopts a combination of two piece/two-piece valve bodies, with the valve seat and valve body lining integrated. When the valve is working, only the full plastic valve seat and the lined plastic butterfly plate come into contact with the medium, and the valve can withstand the medium introduced by the lining material. Corrosion resistant, using a four pole sealing structure, the sealing surface adopts temperature resistant and aging resistant SI rubber elastic gaskets, completely achieving zero medium leakage, tight sealing performance, and long service life.

PTFE lined lug butterfly valve uses fluoroplastic PTFE as the lining material. Polytetrafluoroethylene (PTFE), commonly known as the "plastic king", is a high molecular weight polymer polymerized from tetrafluoroethylene as a monomer. White wax like, semi transparent, excellent heat and cold resistance, can be used for a long time at -180~260 ℃. Therefore, the lining material used for valves has strong applicability, corrosion resistance, low temperature resistance, and high temperature resistance.

PFA lined lug butterfly valve uses fluoroplastic PFA as the lining material. PFA plastic is a copolymer of a small amount of perfluoropropyl perfluoroethylene ether and polytetrafluoroethylene. Compared with polytetrafluoroethylene, the melt adhesion is enhanced, the melt viscosity is reduced, and the performance remains unchanged. Therefore, using PFA as the inner lining of the valve has strong anti-corrosion and wear-resistant functions.

FEP lined lug butterfly valve uses fluoroplastic FEP as the lining material. FEP stands for Fluorinated Ethylene Propylene, translated as Fluorinated Ethylene Propylene Polymer. The English product name: Teflon * FEP is a type of chemical substance. FEP is a copolymer of tetrafluoroethylene and hexafluoropropylene.

The fluorine lined lug butterfly valve has strong corrosion resistance and can effectively ensure the safety of pipeline equipment through various acidic and alkaline media.
