The pressure independent control valve R206A (PICV), combines an automatic control of the flow rate with an optional control of the valve throught an actuator. The valve is able to regulate the flow rate and keep it constant as the differential pressure conditions vary within the hydraulic circuit in which it is installed.

The valve can be used with two operating modes:

• pressure independent flow rate control (with K281 actuator installed) in accordance with the thermal load requirements of the circuit section to be controlled;

• limitation of the flow rate and/or shut-off of the fluid (without actuator or with R473/R473HE thermo-electric actuator installed).

Flow rate adjustment is guaranteed within the declared differential pressure range, with a maintained error of ± 10 % on the controlled flow rate value. The valve is equipped with pressure outlets for measuring the differential pressure in combination with a differential pressure gauge and its own probes.
