The Cashco 521 TFE lined globe control valve is bellows sealed designed to provide superior long-term performance and maximum corrosion resistance in pure chemical service.

The design allows for all wetted internal parts to be machined from a solid block of isostatically compacted, virgin TFE, thus ensuring maximum density and the lowest possible permeability.

An additional design benefit is that the wall thickness integrity is ensured as a result of the TFE body being internally machined after it is secured in a cast 304 SST body shell, thus preventing distortion problems related to the plastic stability of TFE. There is simply no better design or materials available when consideration is given to corrosion resistance and thermal stability.

Applications

Designed specifically for corrosive chemical use, including most hazardous or toxic fluids. Ultimate performance when handling chlorine (wet or dry); bromine; hydrochloric, sulfuric, nitric, and hydrofluoric acids; and most industrial reagents. Also performs well in alkaline or strong basic fluids and most organics. Refer to technical pdf for “Chemical Resistance” and application information.
