Product Details

Product Structure Features

The electric ventilation butterfly valve is designed in the form of a central line butterfly plate, making it have small flow resistance, large flow, and easy operation. It is often used in dust containing systems and cold or hot air gas pipelines in industries such as chemical, building materials, and power plants as a gas medium to regulate flow or cut off devices.

The Main Structure Features Include

1. The 90 degree swing opens quickly to meet the fast closing condition;

2. Bearing external structure prevents medium in the pipeline from entering the bearing;

3. Large diameter rolling bearings are used, with low friction and torque.
