DAC Worldwide's Downsized 3-Way Control Valve Cutaway (256D) is an economical, sectioned valve sample that allows for convenient classroom training in the operation, construction, and maintenance of a pneumatically-operated, 3-way control valve. Through carefully-planned sectioning, 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.
