Powers PB417 - HydroGuard Series PB410 4-Port Pressure Balancing Valve

Series PB410 HydroGuard? Pressure Balancing Valve features heavy, cast brass construction, a poppet type equalizing valve which offers a distinct advantage: it will not stick because of lime build-up or foreign particles in the supplies. The adjustable metal-to-metal temperature limit stop prevents accidental scalding caused by our adjustment of the handle. It also features integral checkstops, back to back and shallow installation. PB410 series is listed to ASSE 1016-P and certified to CSA B125 standard.
