MT4000A/B 霍尼韦尔风门执行器

 


MT4000A/B series

APPLICATION
The MT4000, MT4001, MT4002 and MT4003 are servo
motors to control and govern air lock of gaseous and liqued
fuels.
The servo motors are suitable for burners with small to
medium capacity.
Contents
The MT4000 series are for general use on combustion air
dampers and VF5000 butterfly valves. The A version is used
with separate power lines to drive the motor to high fire or low
fire position. The B version is used in combination with a relay
to allow the motor to drive to high fire when the relay is
energized and drive to low fire when the relay is
de--energized. There are 2 micro switches for auxiliary use.
