Electrical Damper Valve

Damper is a common equipment in the air supply system, electric damper is composed of electric actuator and damper.The adjustable electric damper can adjust the opening degree of the damper and control the air volume.Two - position electric damper opens and closes.

Electric damper is divided into electric round damper and electric square damper

The circular louver damper is used with the electric actuator, which has the advantages of small opening and closing torque, sensitive action, reliable performance, large diameter and light weight.Widely used in metallurgy, building materials, electric power, petrochemical, light industry and other industrial sectors fan, air conditioning, electric dust and all kinds of large pipelines, dust, gas for electric or manual regulation and cut off.

Rectangular multi-blade ventilation butterfly valve, composed of multi-blade.The Angle travel electric actuator is adopted to drive the blade through the connecting rod mechanism to achieve the purpose of regulating medium flow.

Rectangular multi-blade butterfly valves are widely used in power stations, metallurgy, mining and environmental protection, heating and ventilation gas pipelines to do regulation and control medium flow rate use.The light butterfly valve has the form of round butterfly valve, rectangular single plate and rectangular multi-plate butterfly valve.And other light ventilation butterfly valves can be made according to user requirements.
