NIBCO, MB386AF, W51BF-E-GO, Butterfly Valve - Model B, Corzan® CPVC Schedule 80, EPDM, 3"
The Chemtrol® Model B butterfly valve is a wafer style valve with low flow restriction. The valve's injection molded CPVC 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. 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.
