Product Advantage
PTFE has extremely high chemical resistance and can resist corrosion from most acid and alkali substances, so the PTFE seat and PTFE lined disc are suitable for piping systems with corrosive media.
The PTFE butterfly valve also has excellent heat and cold resistance and can maintain stable performance under extreme temperatures.
PTFE material has a very low coefficient of friction, which helps to reduce operating torque and makes the operation of butterfly valves easier and smoother.
Difference between PTFE Seat of PTFE Liner:
The PTFE valve seat is wrapped on the hard rubber backing and directly formed into the overall structure of the valve seat.
Installed in the valve body to provide sealing performance.
PTFE lining is a layer of PTFE that is applied to the inside of the valve body, including the end faces where it connects to the pipe.
PTFE-lined Disc and PTFE seat butterfly valves are widely used in chemical, pharmaceutical, power generation and other industries. These valves are specifically designed to control the flow of corrosive fluids.
The PTFE lining inside the valve offers excellent corrosion and high temperature resistance, making it ideal for a variety of industrial applications. The wafer style design of these butterfly valves makes them lightweight and easy to install between flanges.
PTFE seat wafer butterfly valves are known for their durability and low maintenance requirements. The valve's disc design reduces turbulence and enables high flow rates, making it a cost-effective solution for industrial applications. The compact design of these valves facilitates installation in industrial environments and saves valuable space.
