An RPZ valve (Reduced Pressure Zone) is a type of backflow prevention device used to protect potable water supplies from contamination. Where are RPZ Valves Used? RPZ valves are often used: At water meter connections On sprinkler system connections to municipal water mains On industrial/commercial facilities connected to city water supplies How are RPZ Valves Used? RPZ valves work by containing two independently operating check valves and a mechanically independent, hydraulically dependent relief valve between them. This design creates a reduced pressure zone between the check valves. If either check valve fails, the relief valve purges water to atmosphere preventing backflow. This protects the public water supply from any potential contaminants in the facility's pipes. Why are RPZ Valves Used? RPZ valves provide maximum backflow protection. Their design meets plumbing codes and health regulations for facilities handling hazardous substances or connected to municipal water supplies. Insulating RPZ valves helps prevent freezing and damage. Our experienced team can produce most custom insulation jackets within a short lead time.
