PTFE LINED GLOBE 2 WAY CONTROL VALVE (MIC– 228)

INTRODUCTION

This type of valve is used extensively in the applications involving severely corrosive and toxic flowing media. Within its pressure limitations, this type of valve may be applied to most media. The PTFE lined body design provides an economical alternative to alloy valve bodies in wide variety of applications.
The PTFE lined globe valve body has carbon or glass filled PTFE trim parts, push down to close action and positive shutoff.

DESIGN FEATURES :

  • Fluid Compatibility- The lined material protects metal parts from process fluid making it ideal
    for controlling severely corrosive media.
  • Economy- Since metal parts are protected from process fluid use of expensive alloys is not
    needed.
  • Integrity- The body design provides a mechanical bond between body and liner, which
    minimizes the potential of body liner separation.
  • Long Life Bellows Seal- provides for absolute gland sealing.
  • Easy in Line Maintenance- The top entry design eases in-line maintenance and minimizes
    transfer of pipeline stresses.
 

QUALITY AND PERFORMANCE GUARANTEE :

  • Produced with Quality Systems accredited to ISO 9001: 2008 by Bureau Veritas.
  • >> Full material certification available for all major component Parts.
  • >> Full guarantee on design and Performance.
  • >> All testing performed to the requirements of ANSI B16.34.
