PTFE Lined Ball Valves
Lined Ball Valves are used for controlling flow of caustic acid, inorganic and organic chemicals, phenols, sulphuric and hydrofluoric chemicals, transferring pipelines. These valves have been developed from 316L grade stainless steel, ductile iron, cast iron and cast steel. Design of these valves conforms to ASTM standards. PFA and FEP resin based versions of these pipeline accessories have 265 degree C and 200 degree C working temperature respectively. Smooth inner structure of these Lined Ball Valves prevents deposition of scale or corrosive substances. External surface of these metal accessories can be cleaned by shot blasting or sand blasting process. PU or epoxy primer based coating of these valves helps to avoid corrosion. Quality of these valves has been verified on the basis of electrostatic and hydrostatic pressure tests.
