All inner surfaces of the Tru-Bloc® bleach ball valve are kept constantly wetted and vented to the upstream side when the valve is in the closed position, eliminating the conditions required for gas accumulation and caustic crystallization in the body cavity. The Tru-Bloc® valve is 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 valve can be easily joined with the flanged end connections. Please refer to Chemtrol technical data sheets, valve selection guides and catalogs for engineering and installation information. Corzan® CPVC Schedule 80 thermoplastics demonstrate excellent mechanical strength over broad temperature range, outstanding underground performance and superior hydraulics. Chemtrol Corzan® CPVC valves are lightweight, easy to install, maintenance-free and will not rust, scale, pit or corrode. Choose Chemtrol® valves for the most reliable, versatile and economical valve option in commercial and industrial applications. Chemtrol® ball valves are backed by a 1-year limited warranty. Because Chemtrol® is a NIBCO brand the flow-control valves are unsurpassed in quality, performance and longevity.
