POPU Valve: PTFE Lined Check Valve
PTFE lined check valve is a kind of relying on the flow of the medium itself, and automatically open and close the valve flap is used to prevent the medium from flowing in the reverse direction of the automatic valve. Applicable to all kinds of strong corrosive media with the industrial pipeline system to do opening and closing devices.
Due to the performance of PTFE in the resistance to strong corrosive media, lined in various types of cast iron, carbon steel, stainless steel valve body or pipe fittings and the outer surface of the valve inner parts, not only can be suitable for different conditions of strong corrosive media, but also can replace the expensive rare metals.
