Nibco® Chemtrol® Chem-Pure® Tru-Bloc® Natural Polypropylene Threaded True Union Ball Valves

The Chemtrol® ball valves are engineered with a self-adjusting seat and upstream and downstream blocking capability to stop flow when an alternate union is removed for servicing the piping system. The original Chemtrol® True Union design allows the valve and operational components to be conveniently lifted from the piping system for repair or replacement. Tru-Bloc® advances the True Union concept with the self-adjusting energizer O-ring, available in FKM or EPDM materials. 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.
