Motorized ball valve

MBA120

  • High flow capabilities
  • Air bubble tight
  • Anti-condensation resistor to prevent condensation
  • Flexible and easy to install

Series MBA120 is a range of 2-way motorized ball valves with actuator for use in heating and cooling system. The valve is air bubble tight according to EN12266-1. The MBA120 series is available in DN15-32 and comes with different type of connections to suit most needs. The actuator is assembled on the ball valve with a metallic spigot that allows to assembly/disassembly the actuator in a secure , simple and rapid way.
