Lined lug type butterfly valve are divided into handle drive, worm gear drive, pneumatic and electric; the valve body is divided into two types: full lining and half lining. Full lining means that the valve seat and valve plate are fully lined with tetrafluoroethylene materials such as PFA/PTFE/FEP ect. Half lining means that the valve plate is not lined, using stainless steel SUS304 or SUS316 and other materials
2/Two-piece Lined lug type butterfly valve
Lined lug type butterfly adopts a 2/Two-piece valve body combination, the valve seat and the valve body lining are integrated, when the valve is working, only the all-plastic valve seat and the plastic-lined butterfly plate are in contact with the medium, and the valve can withstand the medium introduced by the lining material. Corrosion, the use of four-pole sealing structure and the sealing surface with a temperature-resistant and anti-aging SI rubber elastic gasket, completely achieve zero leakage of the medium, with tight sealing performance, long service life.
PTFE Lined lug type butterfly valve
PTFE Lined lug type butterfly valve uses fluoroplastic PTFE as the lining material，Polytetrafluoroethylene (Poly tetrafluoroethylene, abbreviated as PTFE), commonly known as “Plastic King”, is a high molecular polymer obtained by polymerizing tetrafluoroethylene as a monomer. White waxy, translucent, excellent heat and cold resistance, can be used for a long time at -180 ~ 260ºC. Therefore, the lining material used in the valve has strong applicability, anti-corrosion, anti-low temperature and high temperature.
PFA Lined lug type butterfly valve
PFA Lined lug type butterfly valve uses fluoroplastic PFA as the lining material, and PFA plastic is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. The melt adhesion is enhanced, the melt viscosity is reduced, and the performance is unchanged compared with PTFE. Therefore, using PFA as the inner lining of the valve has a strong anti-corrosion and wear-resistant function.
FEP Lined lug type butterfly valve
FEP Lined lug type butterfly valve uses fluoroplastic FEP as the lining material，The full name of FEP is Fluorinated ethylene propylene, which is translated into fluorinated ethylene propylene copolymer (perfluoroethylene propylene copolymer). English trade name: Teflon* FEP is a class of chemical substances. FEP is a copolymer of tetrafluoroethylene and hexafluoropropylene.
The fluorine-lined lug butterfly valve has strong corrosion resistance and can pass through various acidic and alkaline media, effectively ensuring the safety of pipeline equipment.
