‌

Square ventilation butterfly valve is a widely used pipeline control device in ventilation and dust removal systems, primarily for regulating and throttling flow rates of dusty gases, gas pipelines, flue gas pipelines, and other media. Its structural features include a new type of design that uses a central-line disc plate焊接 with short structural steel plates, offering a compact structure, light weight, easy installation, low flow resistance, and high flow capacity, as well as easy operation. The square ventilation butterfly valve is suitable for low pressure difference, large diameter, and high flow applications, particularly in ventilation and environmental protection projects involving dusty cold or hot air gases in industries such as chemicals, building materials, power stations, and glass manufacturing.

Application Scenarios

Square ventilation butterfly valves are widely used in the following scenarios:

Chemical Industry: Used to regulate and throttle dusty gas in the chemical production process.

Building Materials: Used in ventilation and dust removal systems within the construction material industry.

Power Station: Used to adjust gas flow in the ventilation and purification unit of the power station.

Glass: Used to control the flow of dusty gas during the glass manufacturing process.

Structural Features

The square ventilation butterfly valve is constructed with a mid-line disc plate and short structural steel plate welding, featuring the following characteristics:

Compact Structure: Designed to be compact, lightweight, and easy to install.

Low flow resistance: High flow volume, easy operation.

‌Stable Operation: Free from components like rods and bolts, ensuring stable operation and a long service life.

‌Multi-position installation: Suitable for various installation locations, unaffected by the medium flow direction.‌

Installation and Maintenance

When installing a square ventilation butterfly valve, the following points should be noted:

The valve disc must remain in the closed position.

The starting position should be determined by the rotation angle of the butterfly plate.

Butterfly valve with bypass valve, the bypass valve should be opened first before operation.

Install according to the manufacturer's installation instructions, and heavy butterfly valves should be mounted on a sturdy foundation.
