We are reckoned as one of the major Manufacturers, Exporters and Suppliers of PFA Lined Diaphragm Valve. Our self cleaning design PFA Lined Diaphragm Valve is highly acclaimed for better throttling flow or block flow. PFA Lined Diaphragm Valve is the best choice for dirty, contaminated and powder media. The quality and functionally of the diaphragm are crucial for greater fatigue strength under reversed bending stresses and dimensional stability even after many switching cycles and at fluctuating temperatures. Moreover, our PFA Lined Diaphragm Valves are suited to handle erosive and abrasive application.  Our PFA Lined Diaphragm Valves have high density and low permeability.

Salient Features :

  • Meet design specification as per B 16.34 / Flange dimensions as per B 16.5.
  • Testing Standard as per BS - EN 12266 - 1 / DIN – EN - 588 – 1
  • Lining Standard as per ASTM F 1545
  • The Weir type top entry Diaphragm valves provide tight shut-off with comparatively low operating force
  • When require to the replacement of the Diaphragm, the bolted bonnet design permits the dismantling of the valve without removing the valve body from the pipe joint.
  • Convection Isolating valve would require expensive exotic materials to resist the effects of sever corrosion.
  • High permeation resistance lining
  • Soft – sealing, gas tight shut – off
  • Vacuum proof anchored
  • Hermetic – Gland less sealing against the valve bonnet
  • Higher density and lower permeability
  • Face to face confirms to BS 6165
  • Travel position indicator gives clear and positive from any angle
  • PTFE Bearing : Minimizes friction between stem and compressor
  • Exclusive sealing bead design prevents best seal and reducing thermal stresses on the sealing surface
  • Cavity free, poke less design ensures unrestricted flow and low pressure drop
  • Floating tube diaphragm Nut design ensures uniform distribution of the stem closing force and the PTFE Diaphragm reducing cold flow
