  Homologation

  • Compliance with EN 60534-1:2005, EN 1092-2:1997, EN 10226-1:2004

  Installation and use

  • These valves can be installed as mixing valves (constant flow rate, variable temperature), as well as deflection valves (variable flow rate, constant temperature) according to the installation requirements.
  • Easy hydraulic connection.
  • Valve motorization is fast and easy executed with: O24 type servocontrol and T01D coupling group; O34A type servocontrol and T04E coupling group.
  • It is always possible to disconnect the servocontrol in order to operate the valve manually using T05A kit.

  • The hot water which comes from the boiler is mixed with a part of water a bit colder which comes from the return pipeline of the system, the shaped rotor provides the dosing of the two streams in order that the temperature in the delivery pipeline to reach the value required by the control unit.
