Design RSS Lined Globe Valve

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 PTFE/carbon support rings is available for permeating service. 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. An optional N10276 nickel alloy (Hastelloy C276) bellows seal is also available to meet the needs of severe service conditions.
Permeating/Corrosive Service—A heavy duty PTFE bellows with N06455 (Hastelloy C4) support rings is available for permeating services which are also corrosive.
This bellows features a modified PTFE material (TFM 1705) which provides additional permeation protection over the original heavy duty PTFE bellows.
This bellows, used in combination with the optional Hastelloy C stem, provides the highest level of permeation protection in services that are too corrosive for the Hastelloy C276 bellows.
