The seat of the PTFE sealed butterfly valve is made of PTFE, and the valve plate is made of stainless steel.
Compared with butterfly valves with rubber seats, the PTFE valve seat is more resistant to corrosion, high temperatures, and wear;
and PTFE seat is non-toxic, odorless, and meets environmental protection requirements. , safe and reliable to use.
It is suitable for working conditions with weak corrosion or certain requirements for cleanliness.
The PTFE seat butterfly valve is widely used in petroleum, electric power, textile, papermaking and other fields.
The applicable media are mainly water fluids, including domestic water, fire water, circulating water, sewage, waste water, etc.
