Fisher™ RSS Lined Globe Valve

The Fisher RSS valve is intended for use in applications involving severely corrosive and toxic flowing media; and is well-suited for pure media applications; as well. The RSS valve body provides an economical alternative to alloy valve bodies in a wide variety of applications.

• The perfluoroalkoxy resin-lined assembly provides corrosion protection by shielding metal parts from the process media; making it ideal for controlling severely corrosive media.
• Because all metal parts are shielded from the process fluid; the use of expensive alloys is not necessary.
• Lining thickness is a minimum of 5 millimeters at all areas where the valve is exposed to process flow. Transfer molding techniques provide for excellent consistency; density; and low permeability. Transfer molded PFA material is translucent.
• Greater safety under vacuum and high temperature service is achieved by dovetail anchorings which provide a mechanical bond; minimizing the possibility of detachment of the lining from the cast valve body.
• The top entry design eases in-line maintenance.
• The PTFE bellows seal is leak tight and; with proper use and maintenance; can have an expected life cycle exceeding 500;000 full stroke cycles.
