The System2™ Sealing Technology utilizes the upstream seat as a backup to the downstream seat and enhances the sealing of the downstream seat. This insures longer life cycle and performance of the valve with respect to conventional seat designs. Available in sizes 1/4˝ through 2”/DN15 – DN50 in PVC and CPVC materials, the TBH Series are fully pressure rated for 250 PSI/PN16 at 23°C non-shock across all sizes and materials. The TBH Series offers IPS or DIN/EN socket, threaded and flanged end connections.
As part of the TBH family, Hayward also offers the TBH-Z model with a drilled “Z” ball for Sodium Hypochlorite service, as well as the CVH Series with the Profile2™ ball for characterized flow. Additional options and accessories for all models include Hayward’s industry leading line of pneumatic and electric actuators, manual limit switches, and stem extensions. The TBH, TBH-Z and CVH Series are available in bare stem / actuation-ready configurations.
