Models 56D and 75D have molded plastic bodies with polypropylene or PVDF discs. The wafer-style ANSI B16.5 bodies have been engineered to incorporate molded body stops to prevent overtightening of the mating flanges during installation. A spherical disc design improves flow characteristics and lowers operating torque. Industry standard (ISO) top-flange mounting patterns facilitate gear operator, electric or pneumatic actuator mounting. The butterfly valves have non-wetted PDCPD bodies and 403 or 316 stainless steel stems.
