Manufactured on the same principle as Tideflex ® Technologies’ revolutionary all- rubber Tideflex ® InLine Check Valve, the Series 2633 is a simple inline check valve for threaded end pipelines. Simple in design, the Series 2633 consists of a body, two endcaps and an elastomer check sleeve. In the open posi- tion, the sleeve creates a wide, free passage proportional to the flow in the pipeline. On flow reversal, the sleeve closes slowly and completely. The silent, non-slamming Series 2633 InLine Check Valve design eliminates water hammer and facilitates low headloss. Containing no levers, balls, floats or springs to corrode, the valve is virtually mainte- nance-free. The only replacement part is the simple, rugged elastomer check sleeve. This small and simple inline check valve is ideal for liquids, gases, powders, slurries and instrument or plant air as well as in any environment where preventing back- flow is required. The Series 2633 is manufactured in sizes 1/2" to 3". The check sleeve is available in a variety of elastomers to match specific service conditions.
