Standard Resin Specifications :-

  • PFA :   ASTM D 3418
  • FEP :   ASTM D 2116


Service Temperature : -

PFA :-

  • Maximum continuous service temperature : 265° C
  • Melt point:   305° C


FEP :-

  • Maximum continuous service temperature: 200° C
  • Melt point : 260° C


Lining Thickness : - Minimum Lining thickness would be 3.0 mm over all wetted portion.


Chemical Inertness :-

  • PFA/ FEP is chemically inert to most of the all chemicals and solvents with the exception of molten alkali metals.
  • PFA / FEP lined valves are used to convey, and are inert to, these chemicals : All acids including hydrofluoric, sulphuric and aqua regia, all caustic, all chlorides organic and inorganic, all solvents, all bleach solutions, all peroxides, all phenols and any combinations of above materials.
  • Combined with the chemical inertness of PFA / FEP is its unique non-stick property. Thus a PFA / FEP lined products eliminate or minimize the built up of deposits of the products which otherwise reduce flow and affect processing operations.     
  • PFA / FEP Lined Ball Valves Finish :-
  • The interior surface of all valves are clean and free of mold burrs, rust, scale or others that may adversely affect the performance of lining.
  • The exterior surface of all valve bodies are be cleaned by sand / shot blasting and painted by 1 coat of Epoxy primer and 2 coats of Polyurethane Top coat.
  • Products Inspection and Testing :-
  • Hydrostatic Pressure :-
  • Body Test   : 10 Kg/Cm2
  • Seat Test    : 10 Kg/Cm2
  • (Hydrostatic pressure at room temperature using clean water.)
  • Electrostatic Pressure :-
  • Non-destructive high-voltage test at an output voltage of 10,000 V. When electric contact is made, a visible/ audible spark or both occur at the probe if there is any defect in lining.


Visual Inspection :- All surfaces are free from blister, porosity or any other defect. All checks / tests are conducted before shipment.


Storage & Transport :-

  • Each end of valve is protected by specially made rubber cap so that products are capable to withstand normal handling during transport.
  • All the materials are supplied with export wooden case or card box packing depending upon the weight and mode of shipment.
