Model XG-RA-500 retrofit assemblies are customized retrofit valves designed to slip into existing mechanically regulated single or dual duct terminals. The units allow the conversion of constant volume systems to more energy-efficient, variable volume systems. XG-RA-500 assemblies currently fit most brands of terminals manufactured from the 1960s to the 1980s. Units install by removing existing volume regulators and inserting the RA valve.

Customized retrofit valves for existing single or dual duct systems.

Optional flow controllers available on satellite mounted panels.

Pneumatic or electronic control sequences available.

Can be installed, in most applications, without disrupting existing ductwork.
