TBB Series Industrial True Union Ball Valves
1/2" to 4" - PVC, Corzan® CPVC PPL and PVDF
Rugged Construction: Haywards TBB Series Industrial True Union Ball Valves are cost effective, yet rugged enough to stand up to demanding industrial and commercial applications.
True Union Design: This makes these valves very easy to maintain by allowing for easy removal from a piping system without breaking down piping connections. Just unscrew the two assembly nuts and lift the valve body out of the line.
Advanced Design Features: TBB Series True Union Ball Valves are superior performers. They have a threaded seal carrier that allows the seat to be adjusted while mantaining downstream presssure. These valves feature a dovetail ball and stem, and a thick double o-ring stem seal for twice the leakage protection of valves with only a single stem seal.
Actuator Mounting Design: For actuator mounting, the valve incorporates a unique design of two holes in the stem body that allows the actuator mounting bracket to mount directly to the valve without the need for glued or clamped-on mounting pads. This assures proper alignment of the actuator to the valve without creating any damaging side loads to cause premature stem seal failure. With this design, the valve can easily be adapted to manual operation should the need ever arise.
Never a Problem with Corrosion: ecause of the valves all plastic construction, they will never rust or corrode and they can survive corrosive environments without the need for painting or expensive epoxy coating.
