        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.

        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.
