The Chemtrol Model-C Butterfly Valve is intended for general water applications. With National Sanitation Foundation (NSF) listing, it is ideal for potable water service. The Model-C valve has also been successfully used to handle mild acidic solutions and medium concentrations of alkaline solutions. However, this valve should not be used in water lines receiving chlorine gas or bleach injection. Nor should it be used in aquatic center recirculation lines, which receive low level bleach injection. Simple construction of the Model-C butterfly valve results from its unique design. It does not have a traditional rubber seat inside the bore of the one-piece molded body. Rather, EPDM is molded over a brass disk. This EPDM material is compressed between the brass portion of the disk and straight bore through the PVC body and creates the sealing mechanism for this butterfly valve. At assembly, two hardened 416 stainless steel shafts with splines on the inboard ends are swaged into the brass inner disk to become the upper and lower stems. Features Glass-filled PTFE bearing-bushings, extending almost the entire lengths of the upper and lower stems, transfer the hydraulic side load on the disk and evenly distributes it to the valve body to ensure low bearing stress with long, trouble-free operation. Rigid brass disk is encapsulated with EPDM. Durable one-piece molded PVC body. Built-in O-ring face-seals require no gaskets between mating flanges. Refer to the Chemtrol Valve Actuation Guide for a full selection of electrical and pneumatic actuators with accessories, including plastic housings. Mounting kits are available for field or factory assembly
