API609 Wafer End One Piece Body Resilient Seat Manual Butterfly Valve With Actuator
Wafer butterfly valve with epoxy-coated ductile iron body are designed to control various media in a commercial and industrial application. Valve mounts between two standard ANSI/ASME Class 125/150 flanges. Seat to flange sea, eliminates the need for flange gaskets. Disc is precision machined 316SS for maximum corrosion resistance. Two piece stem and disc design enhance the flow capacity and reduces turbulence.
