• HOMOLOGATION AND INSTALLATION
  Homologation

  • Complies with EN 60335-1 standard.

  Installation and use

  • Vertical or horizontal mounting position.

  • Ball valves are operated by a rotary servocontrol with bidirectional rotation.
  • Suitable for hot and cold water, antifreeze up to 50% of the volume.
  • To ensure a stable regulation, valve flow rate must be complementary to the nonlinearity of the heat exchangers of heating
    systems.
