Vent-Tech Model WTR

Completely Redesigned for Superior Performance

The Vent-Tech Model WTR Water Valve brings together over 13 years of manufacturing expertise and advanced patent-pending flow design to deliver exceptional performance in clean water systems. Built to enhance flat float air/vacuum valve technology, the WTR provides reliable air release, vacuum relief, and surge protection in a wide range of operating conditions.

Engineered for efficiency, longevity, and precision, the WTR is ideal for clean water applications where consistent performance is essential. For valve sizes 3 inches and larger, we recommend specifying the Model WTW for optimal results.
