Baumannt NV Electric Actuator
with 24000 Control Valves
The Baumann NV electric control valve series is
specifically designed for Baumann sliding-stem control
valves. It is used for temperature and humidity control
for HVAC (hot and chilled water, steam, glycol, etc.),
semiconductor manufacturing (clean rooms, make-up
air handlers, recirculation air handlers, humidification,
chillers, jackets, and glycol systems) and for many
more industrial environments (textiles, food and
beverage, and tire manufacturing).
