Stainless steel pneumatic ventilation butterfly valve

Ventilation butterfly valve used in chemical industry, building materials, ventilation, environmental protection engineering in power plant, glass and other industries of dust in the cold or hot gas pipeline, the gas medium to adjust flow or cut off the pipeline control unit. This valve shall generally be installed in the pipeline.

Introduction to the

Butterfly valve is a kind of simple structure of the regulator, at the same time can also be used for low pressure pipeline medium switch control.

Electric ventilation butterfly valve

Ventilation butterfly valve is a kind of closed type butterfly valve.

Ventilation butterfly valve used in chemical industry, building materials, ventilation, environmental protection engineering in power plant, glass and other industries of dust in the cold or hot gas pipeline, the gas medium to adjust flow or cut off the pipeline control unit. This valve shall generally be installed in the pipeline.

Main products: large ventilation butterfly valve, electric valve, the leakage rate of 0, explosion-proof ventilation butterfly valve.

Structural characteristics of

1. The middle type disc plate and short structure is a new type of structure design and manufacture of the steel plate welding, compact structure, light weight, easy installation, small flow resistance, big circulation, avoid the influence of high temperature expansion, convenient operation.

2. No the connecting rod, bolts, etc., reliable operation, long service life. Can be installed in a transfer, not affected by the medium flow direction

use

Ventilation butterfly valve is a kind of closed type butterfly valve, widely used in building materials, metallurgy, mining, power and other production process of medium temperature 300 ℃ or less on the pipe nominal pressure of 0.1 Mpa, to connect and open/close or adjusting medium quality.

Ventilation butterfly valve

Working principle of the 2

Ventilation butterfly valve can be divided into manual and electric drive, can be driven by motor or turbine driven actuators, make the disc plate freely within the range of 90 ° rotation to achieve the goal of open/close or adjusting medium flow.
