This Chemtrol Model B butterfly valve is a wafer style valve with low flow restriction. The valve's injection molded PVC construction with EPDM seat is ideal for use in chemical applications. The disc and stem sheath are molded over a 316 stainless steel hex shaft to make a one-piece assembly. With this unique dry shaft seal, liquid never contacts the shaft, even at maximum pressure. The leak-proof design incorporates vulcanized bushings and double O-ring seals. The valve is easy to install but cannot be used as an isolation valve. Please refer to Chemtrol technical data sheets, valve selection guides and catalogs for engineering and installation information. 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. Chemtrol PVC 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 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.
