        产品介绍
        • 产品型号: FisherRSS
        • 产品类别: FisherRSS系列直通调节阀

        Fluid Compatibility—The PFA (perfluoroalkoxy resin)-lined assembly provides corrosion    protection by shielding metal parts from the process media, making it ideal for controlling severely corrosive media.

        Permeating Service—A heavy duty PTFE bellows  with  stainless  steel  support rings is standard for all  services in the 1- to 4-inch valve sizes. Compared to a standard bellows, the heavy duty bellows  design has an enhanced resistance to permeation. This is due to a wall thickness of 2.5 mm (0.1 inch) and pressure  retaining  rings  inside the bellows. This bellows features a modified PTFE material (TFM 1705) which  provides  additional  permeation protection over the original heavy duty PTFE bellows.
        Economy—Because all metal parts are shielded from the  process  fluid, the use of expensive alloys is not necessary.
        Liner Integrity—Lining   thickness is  a minimum  of 5  millimeters   at all  areas where the  valve  is exposed to process flow (3.5 millimeters minimum thickness for 0.5 inch  and  0.75 inch  valves).  Transfer molding  techniques provide  for excellent consistency, density, and low permeability.  Transfer molded  PFA  material is translucent. This allows for checking of the entire wall surface for pin holes and cracks in  the  material during the manufacturing process.
