The manual ventilation butterfly valve is made of the same material as the valve body and processed into a sealing ring, using electric or pneumatic transmission. Its applicable temperature depends on the material of the valve body, with a nominal pressure of ≤ 0.6MPa. It is generally suitable for use in industrial, metallurgical, environmental protection and other pipelines for ventilation and regulating medium flow. Its main characteristics are:

1. The design is innovative, reasonable, structurally sound, lightweight, and quickly opens and closes.

2. Small operating torque, easy to operate, labor-saving and agile.

3. Adopting suitable materials to meet different medium temperatures such as low, medium, and high, as well as corrosive media.

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.

Purpose 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 valve is made of welded materials, with good performance, stable and reliable 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 applications. It is used in combination with various actuators to form valves with different performance.
