EMV 110 602/1590 B

motorized ball valve with a battery support operation

FIRŠT actuators, series EMV 110 602/1590 B is used in system, where in case of power failure opens/closes ball valve. It can be used as safety element in various systems. Valves are available in (DN 20 - DN 32).

  • Manual ball valve opening/closing possibility.
  • Setting the position of the ball valve in case of power failure - open/closed.
  • Sound signaling possibility - additional connection of beeper.

When the Firšt EMV 110 602/1590 B actuator is pluged in a electrical voltage it goes automatically in home position - closed (default or factory setting). In case of power failure the actuator is using battery power to open the valve. The actuator also has an output, which can be used for acoustic signaling in case of power failure (beeper 4-7 VDC - uses battery power). However, this shortens battery life.

Installation examples

In case of power failure it opens the flow, which passes all control elements. The installation must be executed properly, that it allows water circulation in the system.


Protection of elemnts of the system:

In case of power failure it closes return line, thus prevents overheating of heat exchanger.
