Aira 4Matic Global Valve Automation Pvt. Ltd.

Lined valves and accessories use fluorocarbons such as PFA, PVDF, PTFE, PFA-AS (antistatic), as per customer request.

Fluorinated Ethylene Propylene (FEP) is a resin coating that has a very high chemical and temperature resistance. FEP is highly inert and will withstand exposure to most chemicals and solvents such as Acetic acid, Acetone, Alcohols, Ammonia, Aromatic solvents, Chlorine, Citric acid, Detergents, Diesel, Fluorinated refrigerants, Fruit juices, Glycols, Hydrogen Peroxide, Hydrochloric acid, Nitric acid, Petrol, Gasoline, Kerosene and Sulphuric acid.

FEP has a high melting point and can be used in environments as high as 200°C (392°F).

FEP is often specified for liquid level measurements applications such landfill leachate monintoring, fuel tank level and chemical storage tanks.

PerFluoroAlkoxy (PFA) offers similar properties to FEP, but is considered more of a premium resin. PFA is preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. PFA offers high melt strength, stability at high processing temperatures, excellent crack and stress resistance, a low coefficient of friction, and more than 10 times the Flex life of FEP.

It has high resistance to creep and retention of properties after service at 500°F (260°C), with useful properties at -320°F (95°C). PFA also meets FDA 21CFR.177.1550.

PFA is used in the same types of applications as those listed above for FEP.
