Round multi-blade butterfly valve
DYD-Y series round multi- blade butterfly valve
Structural features and applications
This series of round multi- blade butterfly valves are widely used
in the dusty cold air or hot air gas pipelines of ventilation,
environmental protection engineering in metallurgy, building
materials, chemical industry, power station, glass and other
industries, especially suitable for the inlet and outlet of fans as
air flow regulating and hoisting devices, so as to reduce the
opening and closing torque of the fan, and can be combined with
various actuators to form different device performance.
