DAC Worldwide's Downsized Butterfly Valve Cutaway (254D) is an economical, yet realistic, sectioned valve sample allows for convenient classroom training in the design, construction, and maintenance of industrial concentric, wafer-type resilient seat butterfly valves. Through carefully-planned sectioning and color-coding, the complete internal configuration of the valve is exposed and showcased. Seal features and hardware locations have been retained, allowing for “hands-on” training in maintenance. This economical, tabletop sample supports training in a variety of process-related industries.
