Introduction To Common Types Of Ptfe Lined Valves
Lined Valve Common Types
When it comes to PTFE-lined valves, polytetrafluoroethylene resin is used to press the inner wall of the valve pressure-bearing parts (this method is applicable to all types of pressure vessels and internal accessories of pipelines) or the outer surface of the valve parts by molding, which has strong corrosion resistance.
Now when talking about PTFE-lined valves, we can talk about several common types of valves. Fluorine-lined check valves (also called one-way valves) are valves that only allow the medium to move in one direction and prevent reverse flow. The closing part of the fluorine-lined stop valve moves along the center line of the valve seat. In this form of valve movement, the change of the valve seat port is proportional to the valve stroke. The wafer-type fluorine-lined butterfly valve uses a fluorine plastic lined butterfly plate with a spherical sealing surface, and a silicone rubber gasket valve seat to adjust the sealing performance. It has a tight sealing performance and a long service life, which can quickly cut off or adjust the medium flow. With the development of the valve industry, the PTFE-lined valve industry is also constantly updating.
