Vent-Tech Model RAW
Engineered for Demanding Raw Water Environments
The Vent-Tech Model RAW Water Valve is purpose-built for raw and re-use water installations, delivering reliable air release and vacuum relief in systems where untreated or reclaimed water is sourced directly from natural or municipal surroundings. Engineered to seal at zero psi, the RAW valve maintains consistent performance and protection even in low-pressure applications.
This model is designed to handle environmental debris such as leaves, silt, and organic material commonly found in groundwater, rainwater, surface water, lakes, rivers, effluent, wells, and re-use systems. It is NSF certified, ensuring safety and compliance for appropriate applications.
The RAW valve is not intended for use with raw sewage or industrial wastewater containing grease, chemicals, or heavy contaminants. For engineers managing raw and re-use water systems, the Model RAW offers a dependable, precision-engineered solution built for nature’s toughest elements.
