Product Description

PTFE (FEB PFA) Lined Ball Valve

  • BALL VALVE is particular type of rotary valve used in Engineering Industries.
  • It is generally used in fluid handling system for flow control.
  • These type of rotary valves are fixed for corrosive applications.
  • Ball valves are used in many industries like Petrochemicals, Chemicals, Pharmaceuticals and Food, Vacuum Service, Clean Liquids and Gases, Corrosive Liquids and Gases, Hazardous Liquids and Gases Viscous Liquids, Dry Materials, Processing

Specifications:

Ball Valves are excellent in chemical applications, including the most challenging services (e.g. dry chlorine, hydrofluoric acid, oxygen). They are easy to operate, have standard face-to-face dimensions, high flow capacity, high pressure/temperature capabilities and ability to handle severe service chemicals.

Ball valves are considered high recovery valves, meaning a low pressure drop and relatively high CV, [coefficient of flow (GPM per 1 PSI pressure drop).

The benefits of these desirable flow parameters are reduced pump size and less system wear due to lower velocity.  The ability to provide fire safe protection and handle severe service chemicals are two of the significant advantages of the ball valve.  Can be installed either vertically or horizontally depending on the type of application.

Why PFA / FEP Lining?

In the chemical industry, both Fluor polymers - PTFE and PFA/ FEP- are used mainly in the form of linings.
For simple shapes, such as pipes, bends, T-pieces or reduction joints, PTFE is generally used. Using PTFE for lining of complicated shapes, such as valves is more difficult.
PFA / FEP, a thermoplastic material with a well-defined melting point, is processed by means of injection molding.
This method enables very precise wall-thicknesses to be achieved, with tolerances of less than 0.5 mm, even at tight radii and in undercuts. Practically no mechanical finishing is needed for lined parts.

PFA/ FEP properties include:

  • Chemical inertness
  • Negligible moisture resistance
  • Stress - cracking resistance
  • Wide service temperature range
  • Better sealing & wear resistance between parts -it is moldable & machinable to close tolerances.

Lined Ball Valves

  • Outer body graded cast iron as per ASTM Standard, other materials like cast steel / stainless steel available on request.
  • Lined ball valves offer high stability, rigidity eliminating potential leak path.
  • Bubble tight shut off: precision machined ball and seat ensures leak free Valve.
  • One-piece ball & stem: no possibility of damaging PFA/FEP Lining on ball by the stem
