It is recommended to install a filter prior the R206A valve to prevent damage or blockage due to debris. Further, it is recommended not to exceed maximum differential pressure control range of the cartridge. Note. Failure to abide by all recommendations as per this installation and operation instruction will void warranty. R206A Cartridge setting adjustment To adjust the setting of the cartridge according to the desired flow rate, proceed as follows: 1) Remove the cartridge plug; 2) Using a 8 mm wrench, rotate the stem of the cartridge clockwise to decrease the setting; counterclockwise to increase the setting; 3) Replace the cartridge plug. 1 2 3 8 mm8 mm8 mm R206A

Description

R206A balancing valves maintain a constant flow rate of the fluid as the upstream/downstream pressure difference varies. The set flow rate is guaranteed inside the declared range of differential pressure, with a maximum mistake of ± 5 % on controlled flow rate values, or ± 2 % on the maximum flow. The balancing valves automatically balance the hydraulic circuit and ensure the design flow rate. They are composed of a brass body, with female- female connections and prearranged for the connection of sensor holder, to measure the differential pressure, and they have a cartridge that can be replaced if needed. It can be calibrated through a key that compensates the differential pressure by guaranteeing the flow rate constancy. A double indicator, having 1 to 5 scale and decimal decision from 1 to 9, permits precise flow rate regulations (please refer to the “Flow rate diagrams” paragraph for the complete regulation tables for the different valve types).

Components for boiler room Dynamic balancing valves R206a Flow rate check To calculate the flow rate of the R206A, you just have to measure the differential pressure, by installing in the housings of the valve the probe holder P206Y001 and by using a differential pressure manometer. If the measured differential pressure value falls within the nominal operating range, then the flow rate through the valve corresponds to the setting set on the cartridge (see “Flow rate diagrams”). Balancing valve R206A + probe holder P206Y001 + differential pressure manometer R225E Probe Differential pressure manometer Warning. Leakage of hot water can occur through the pressure outlets during the sensor introduction of the sensors. Wear protective clothes and glasses in order to prevent personal physical damages during the pressure measure. Do not use lubricants on the sensors to ease the outlet insertion. If needed simply wet the sensors with clean water. Do not leave the measure needle too much time in the pressure outlet, as it could cause leakages.
