Features:
The advantages of (PTFE lined butterfly valve) are as follows:
High temperature resistance - the working temperature reaches 250℃.
Low temperature resistance - has good mechanical toughness; even if the temperature drops to -196°C, it can maintain an elongation of 5%.
PTFE lined butterfly valve Corrosion resistance - It is inert to most chemicals and solvents, and can withstand strong acids and alkalis, water and various organic solvents.
Weather resistant - has the best aging life among plastics.
PTFE lined butterfly valve High lubrication - has the lowest friction coefficient among solid materials.
Non-adhesion - It has the smallest surface tension in solid materials and does not adhere to anything.
Non-toxic - physiologically inert, it can be used as artificial blood vessels and organs for long-term implantation in the body without adverse reactions
PTFE lined butterfly valve is the preferred corrosion-resistant lining material for corrosion-resistant pipes, pipe fittings, corrugated pipes, pump bodies, valves, kettles, tanks, towers and various standard equipment; as a sealing material, it is widely used in the machinery, petrochemical, transportation, textile and construction industries. Widely used; PTFE can also be used as valves, bearings, piston rings, guide rails and other parts that require corrosion resistance and low friction.
