Manual ventilation butterfly valve

Manual ventilation butterfly valve is a structurally simple regulating valve that can also be used for on/off control of low-pressure pipeline media. Its performance has been widely recognized by users.

Manual ventilation butterfly valves are mainly made of carbon steel or stainless steel as raw materials, consisting of handles, baffles, shells, main shafts, connecting flanges, etc., which can prevent the phenomenon of jamming caused by thermal expansion and contraction due to large temperature differences. The air leakage rate is relatively low, the resistance is small, the installation is simple, and there are no rubber components inside, which are not affected by temperature differences and media.

Product features of manual ventilation butterfly valve:

1. Manual ventilation butterfly valve is a non sealed butterfly valve widely used in production processes such as building materials, metallurgy, mining, and power. It is used for connecting, opening, closing, or regulating the medium quality in pipelines with medium temperature ≤ 800 ℃ and nominal pressure of 0.1Mpa.

2. Manual ventilation butterfly valve is a non sealed butterfly valve. Manual ventilation butterfly valves are used in dusty cold or hot air gas pipelines in industries such as chemical, building materials, power plants, and glass for ventilation and environmental protection projects. They serve as pipeline control devices for regulating flow or cutting off gas media. This type of valve should generally be installed horizontally in pipelines.

The manual ventilation butterfly valve is made of the same material as the valve body and processed into a sealing ring. Its applicable temperature depends on the material of the valve body, and the nominal pressure is ≤ 0.6MP. It is generally used for regulating the flow rate of ventilation media in industrial, metallurgical, environmental protection and other pipelines.

The main features of manual ventilation butterfly valve are:

1. The manual ventilation butterfly valve is designed with novelty, rationality, reasonable structure, light weight, and can be opened and closed.

2. The manual ventilation butterfly valve has a small torque, is easy to operate, and is labor-saving and agile.

3. The manual ventilation butterfly valve adopts suitable materials to meet different medium temperatures and corrosive media such as low, medium, and high.

Structural characteristics and uses of manual ventilation butterfly valve:

Manual ventilation butterfly valves are widely used in ventilation and dust removal systems, serving as flow regulators and throttling devices for dusty gases, gas pipelines, ventilation and purification devices, flue gas pipelines, etc. This manual ventilation butterfly valve is welded with good materials, which has stable operation, easy operation, sensitive action, low leakage rate, long service life, and easy installation and maintenance. It is particularly suitable for low-pressure, large-diameter, and high flow situations. It is used in combination with various actuators to form valves with different performance.
