DAC Worldwide's Downsized Lift Check Valve Cutaway (257LD) is an economical, yet realistic, sectioned valve sample that allows for effective classroom training in the design, operation, construction, and maintenance of an industrial lift-type check valve. 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 disassembly and maintenance.
