This full-featured valve is engineered to provide accurate throttling control and shutoff for industrial, chemical and water treatment applications. Weir type design eliminates entrapped fluids in valve and is excellent for handling liquids with suspended solids, viscous fluids and slurries. Available in PVC, CPVC and Glass Filled Polypropylene with a variety of Diaphragm material options. PVC & CPVC 1/2" - 2" valves with Flanged Body, Spigot Body or True Union style Socket & Thread ends or Optional Special Reinforced (SR) Threads, and sizes 2-1/2" - 8" with Flanged Body. Polypropylene 1/2" - 2" valves with True Union style Special Reinforced (SR) Threaded ends and sizes 2-1/2" - 8" with Flanged Body.
Low Profile Design
Minimizes space required to install and operate. Allows compact system planning and engineering in even the most demanding applications.
Multiple End Connector Options
Spigot, flanged, or true union socket/threaded & SR threaded ends provides greater versatility for all applications. Popular true union style features strong buttress threaded union nuts with both socket and threaded end connectors included with each valve.
Heavy Bodied Schedule 80 PVC, CPVC or PP Construction with Mountable Body
Schedule 80 smooth-wall construction provides extra strength and superior chemical and corrosion resistance while maximizing fluid flow. Body can be easily secured to support surface using built-in mounting holes with user supplied self-tapping screws.
Choice of Chemical/Abrasion Resistant Elastomeric or PTFE Diaphragms
Choice of high grade, abrasion resistant EPDM, Viton®, or elastomer backed PTFE diaphragm allows application specific selection for optimum chemical resistance. Diaphragm tab marking provides quick elastomer type identification.
Easy-Grip Handle with Clear-View Position Indicator
High Impact polypropylene handwheel style handle provides a firm grip for smooth, easy operation. Clear-View indicator with highly visible yellow marker shows valve position at a glance.
