  • Product Description
  • Technical parameters

  • Performance ：

    1、 Normally closed, in case of fire, the smoke sensor sends an electrical signal ( DC24V) to the control center, the motor inside the actuator is energized, the valve opens automatically, and outputs an opening electrical signal.

    2、 After the valve moves, the DC motor drives the reset.

    3、 The valve can be opened and reset manually.

    4、 The action signal or reset signal is fed back to the control center and the starting equipment.
