PFA Lined Diaphragm Valve

We’re proud to say that we’re one of the leading brand producing, trading, and supplying PFA-lined diaphragm valves. For superior flow throttling or flow blocking, our PFA Lined Diaphragm Valves have received accolades for their self-cleaning designs. When working with unclean, contaminated, or powder media, a PFA Lined Diaphragm Valve is the way to go. Superior fatigue strength under reversed bending strains and dimensional stability even after several switching cycles and at varying temperatures are dependent on the quality and functionality of the diaphragm. Our PFA Lined Diaphragm Valves are also resistant to corrosive and abrasive media. When it comes to our PFA Lined Diaphragm Valves, density and permeability are two qualities that stand out.

The PFA Lined Diaphragm Valve provides reliable closure with little operator effort. Its design allows for the valve to be disassembled without removing the valve body from the pipe junction, which is necessary for replacing the diaphragm. It has applications in industries like the Synthesis of Organic Compounds for Industrial Use, Development of Plant defence Mechanisms, Manufacturing of Detergents Using Alkali and Chlorine, Purification of Water, Synthesis of Bromine, In-House Food Manufacturing, Therapeutics Preparation, Sugar Manufacturing, Processing Crude Oil, etc.


  • It has a high resistance to penetration
  • Hermetic: Sealing against the valve bonnet with minimal reliance on the gland
  • Superior density and impermeability
  • From every vantage point, the travel indicator provides clear and pleasant feedback.
  • The PFA Bearing: Effectively reduces stem-to-compressor drag
  • Unique sealing bead construction lessens heat strains on the seal’s contact surface and minimizes leaks.
  • Unrestricted flow and little pressure loss are guaranteed. This diaphragm does not contain cavities and holes but has an extremely fine body.
  • The PFA ensures that the closing force on the stem is distributed evenly. 
  • Its diaphragm’s ability to moderate air temperature
