DAC Worldwide's Piston Check Valve Cutaway (295-706) is a sectioned valve sample allows for valuable classroom training in the operation, construction, and maintenance of industrial piston-type check 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. These welded-bonnet, socket-welded valves, commonly used in high pressure oil & gas production applications would be of interest to those involved in oil & gas production operations and maintenance training.
