  • R473, R473M: thermo-electric actuator with zone valves motor funcion.
  • R193K: eccentric kit pipe for installation of 3-ways valves with distribution manifolds. Zone valves are devices for shutting off the heat transfer fluid which, activated by an actuator, allow the subdivision of air conditioning systems into homogeneous sectors from the point of view of room temperature control. The R291, R292 and R292E zone valves are equipped with a piston stopper and can be of the 3-way type, equipped with an adjustable by-pass, or 2-way, which generally requires the installation of a differential valve on the main circuit.
