Features:

  • Pre-assembled for ease of installation
  • Easy service accessibility
  • High capacity fill valve for quick system filling and purging
  • All bronze body construction union solder x NPT connections

Note: Do not use this item for any installation or repair of potable water applications.

                    My radient heat system has required make up water frequently. One morning, the boiler had very low pressure. With this automatic fill valve, the system pressure will now remain at the proper level. This valve is an important addition to any hydronic heating system.

                          This was what was needed to get the boiler pressures down to where they should have been.

                              The 911 has a brass backflow preventer and a bronze PRV/feed valve, while both pieces are brass on the B911 series.

                              A:

                              Not sure what you mean by "refill after purging" ? Purging is accomplished
                              by filling the system at a rapid flow to drive out the air at which point
                              the system should be filled with no air left in the pipes. The fill valve
                              allows high flow when needed for purging but in normal operation is a
                              pressure regulator usually set at 12 PSI.

                              The fast fill mode on the valve is activated using the lever on the top of the PRV half of the unit.
