Chemtrol® Chem-Pure® Natural Polypropylene Socket True Union Ball Check Valves

The Chemtrol® ball check valves stop media flow in one direction while allowing flow in the opposite direction, with minimum turbulence and chatter, while maintaining pump prime. The original Chemtrol® True Union design enables the valve and operational components to be conveniently lifted from the piping system for repair or replacement. Chemtrol® Chem-Pure® polypropylene exhibits an extremely low content of metals, organic compounds, and free ions, and no pigments or other adulterants (natural) are added to the plastic resin. Chem-Pure® natural polypropylene demonstrates excellent chemical resistance properties, including aqueous solutions of acids, alkalis and salts, and several organic solvents, making it ideal for use with deionized water systems, clean chemical processes, pharmaceutical operations, and food processing.
