Refurbishments insert AGA

The refurbishment inserts RNT / NIA replace the insert in 2-pipe and 1-pipe radiator manifolds made by AGA / Thermopanel 1970-1988. The replacement inputs RNT / NIA are regulated with a thermostat, thermal actuator or handwheel. AGA / Thermopanel's radiator coupling is characterized by a grey plastic steering wheel with wings or a grey transparent thermostat. The manifold has a blue or red tape on the inlet pipe. Refurbishment insert RNT has an exact presetting function hidden under the stuffing box, the presetting is done with a preset key FN by opening the number of revolutions from the closed valve acc the pressure drop diagram. NIA insert does not have presetting.
