A purge and fill valve is a vital component in any closed-loop system. Hydronic heating, solar thermal, or radiant floor heating systems all rely on efficient circulation of fluid, and the presence of air pockets can quickly compromise performance. Air trapped inside can cause noise in pipes, corrosion of internal components, uneven heating or cooling, and an overall reduction in system efficiency.
Having precise control over air removal as well as system filling and draining helps to prevent these issues. RED-WHITE VALVE’s purge and fill valves are an excellent solution. They streamline maintenance and provide reliable performance for long-lasting efficiency and dependable operation.
