Overview
The Nibco Chemtrol 1-1/4″ Tru-Bloc true union ball valve is designed for reliable shut-off and flow control in demanding industrial, chemical, and plumbing environments. The Tru-Bloc true union ball 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 double union design of these valves permits in-line maintenance without disconnecting pipe.
Key Features
- Tru-Bloc advances the True Union concept with the self-adjusting energizer O-ring.
- The valve and operational components can be conveniently lifted from the piping system for repair or replacement.
- Chemtrol PVC valves are lightweight, easy to install, maintenance-free, and will not rust, scale, pit, or corrode.
- Full port design for optimized flow characteristics.
- Backed by 1-year limited warranty.
Technical Specifications
The 1-1/4″ Tru-Bloc valve is constructed for chemical processing and industrial applications. The valve’s injection molded PVC construction with EPDM O-ring is ideal for chemical processing, industrial plating, chilled water distribution, chemical drainage, and irrigation systems. PVC Schedule 80 exhibits excellent corrosion resistance properties and has the highest long-term hydrostatic strength of any other major thermoplastic material used for piping systems.
Typical Applications
- Chemical processing and chemical drainage systems
- Industrial plating operations
- Chilled water distribution and HVAC systems
- Irrigation and agricultural water systems
- Plumbing systems requiring reliable shut-off control
- Corrosive liquid handling and waste treatment
