Damper

High Temperature Hot Air Metallurgy Damper Butterfly Valve has the characteristics of high temperature resistance, high pressure range and large nominal diameter.

The valve body is made of stainless steel, and the sealing ring of valve plate adopts metal ring instead of rubber ring. Large high temperature butterfly valve is made of steel plate welding, which is mainly used for flue gas duct and gas pipeline with high temperature medium

The valve body and valve disc are welded with high quality carbon steel plate or stainless steel plate.
Stainless Steel Manual Butterfly Air Damper has the advantages of simple structure, small flow resistance, light weight, flexible rotation, long service life and convenient operation and maintenance.
Stainless Steel Manual Butterfly Air Damper can be used with various actuators to form different performance equipment.

Fit anywhere in ducting, at any altitude.
Compact, no bonnet, little external clearance needed.
Lightweight
Drive and linkage more readily accessible
Control function simple with opposed blades.
Thin metal blade construction gives quick response to thermal transients.
Fast opening and closing.
Low leakage to outside environment.
Good modulation and control characteristics.
Actuation power requirements are low.
Normally does not require a support structure.

1. Industrial Shut Off Damper Valve is designed and manufactured by adopting the new structure form of welding the central line type disc plate and short structure steel plate, with compact structure, light weight, easy installation, small flow resistance, large flow capacity, avoiding the influence of high temperature expansion, and easy to operate.

2. There is no connecting rod, bolt, etc. inside, it works reliably and has long service life. It can be installed in multiple positions, not affected by the flow direction of medium

purpose

Fabricated Butterfly Dampers Valve has the advantages of compact structure, easy installation, small flow resistance, large flow capacity, avoiding the influence of high temperature expansion, and easy to operate.

1. The structure dimension is short, the weight is light, and the installation is convenient
2. Small driving torque, flexible opening and closing, convenient operation
3. There is no visible gap between the sealing pairs and the leakage rate is small
4. The expansion gap between butterfly disc and valve body is large, which can effectively prevent the jamming caused by heat expansion and cold contraction
5.The valve can be equipped with a variety of driving devices, such as manual device, worm gear transmission device, pneumatic device, electric device. Ventilation butterfly valve is widely used in metallurgy, petrochemical, electric power, building materials, mining and other industrial pipelines

Simple structure, small flow resistance, light weight, flexible rotation, long service life, convenient operation and maintenance

The shaft end is sealed with flexible graphite braided packing, which has the characteristics of high temperature resistance and self lubrication

It is especially suitable for large diameter, large flow and low pressure difference

It can be used with a variety of actuators to form different performance equipment

The structure of the Ventilation Damper Butterfly Valve is welded by using the center line butterfly disc and short structure steel plate, so there are no connecting rod, bolt and other components in its internal part, so there will be no component problems in the use process, so the failure rate is very low. It's very convenient to use. It is a reliable ventilation butterfly valve device. And because its sealing system is metal sealing, so the service life is longer than elastic seal, and has the characteristics of high temperature resistance. So it is widely used in building materials, electric power, metallurgy and other industries. In the temperature can be higher than 300 degrees in the medium pipeline, can be perfectly connected and closed regulation. Ventilation butterfly valve can also be customized according to the needs of customers.
