The Xylem-Bell & Gossett FB-38TU Union-Pressure Reducing Valve Set is a high-performing valve for use in hydronic HVAC systems but is especially designed for hot water heating circulations. It has a fast-fill operation and 1/2″ NPT connections that keep the system pressure at a preset 12 PSIG, to provide proper operations and safety of the system. It is easy to install because of its union connection. This is normally used in boilers, expansion tanks and other such HVAC equipment. Benefits of the systems include protection from over-pressurization, constant operation of systems and less damage to components of the system.
