D341W Ventilation and explosion-proof butterfly valve is used in dusty cold air or hot air gas pipelines of ventilation and environmental protection projects in chemical, building materials, power stations, glass and other industries, as a pipeline control device for regulating flow or cutting off the gas medium. This type of valve should generally be installed horizontally in the pipeline.

The main features of D341W manual ventilation butterfly valve are:

1. Novel and reasonable design, unique structure, light weight, and rapid opening and closing.

2. Small torque, convenient operation, labor-saving and dexterous.

3. Use suitable materials to meet the requirements of low, medium and high medium temperatures and corrosive mediums.

Structural characteristics of D341W manual ventilation butterfly valve

1. It is designed and manufactured with a new structure welded by a midline butterfly plate and a short structure steel plate. It is compact in structure, light in weight, easy to install, small in flow resistance, large in circulation, avoids the influence of high temperature expansion, and is easy to operate.

2. There are no connecting rods, bolts, etc., so it works reliably and has a long service life. It can be installed in multiple stations and is not affected by the flow direction of the medium

Ventilation butterfly valve is a non-closed butterfly valve, which is widely used in the production process of building materials, metallurgy, mining, electric power and other production processes on pipelines with a medium temperature of ≤300℃ and a nominal pressure of 0.1Mpa to communicate, open and close or adjust the flow of the medium.
