The Anval RFS valve is designed in a manner that creates additional sealing performance through the use of a ‘Floating Shoe’. This is where the ceramic embedded rotor ends create a seal with an adjustable shoe as opposed to the body; as the shoe wears, the seal can be maintained by adjusting the external bolts to push the shoe against the rotor. This mechanism completely avoids wear in the body and, therefore, an increased level of consistency and performance throughout the extended life of the RFS valve.Anval also recommended the use of its SG Series Slide Gate Valve to work in collaboration with the RFS and allow for the effective isolation of the unit for maintenance to the furnace. Based on the figures provided by Brightwater, Anval determined that the most appropriate sizing for this application would be the RFS750 paired with the SG750.
