PTFE Valves are developed to cater to the process where very corrosive fluids are involved and cost of exotic metals becomes prohibitively expensive apart from scarce availability.
PTFE ( Poly Tetra Fluro Ethylene) being inert is corrosion resistant to most of the fluids.
However, PTFE Valves have limitations with regards to Pressure and Temperature.
