Ventilation butterfly valve with carbon steel flange connection for regulating air flow and high-temperature resistant industrial pipelines

Description :

This ventilation butterfly valve is designed specifically for industrial ventilation systems and is suitable for regulating the flow rate of pipeline media in industries such as metallurgy, chemical engineering, and power. The valve body structure is compact, lightweight, and easy to install and maintain. Adopting a midline structure design, the sealing performance is reliable and can effectively control the flow and cutoff of gas media. Maintain stable operating torque during long-term operation, reduce the load on the actuator, and extend the service life of the equipment.

The valve plate is precision machined, with a smooth surface and low flow resistance coefficient, which helps to reduce system energy consumption. The sealing ring is made of high temperature resistant and corrosion-resistant materials, which can adapt to temperature changes and medium characteristics under different working conditions. Whether it is ambient temperature air or dusty gas, it can maintain good sealing effect, prevent leakage, ensure the cleanliness and safety of the production environment, and meet environmental emission requirements.

The driving mode is flexible and can be equipped with manual worm gear box, pneumatic actuator or electric device to achieve local or remote automatic control. The handle operation is effortless, the scale is clear, and it is easy to accurately adjust the opening. Unified automation interface standards, compatible with various DCS and PLC control systems, improving overall automation level. Smooth switching, no impact, protecting the pipeline system from pressure fluctuations.

The valve body material is usually carbon steel or stainless steel, with high strength and good pressure resistance. The flange connection complies with national standards, has strong interchangeability, and is easy to connect with existing pipeline systems. The surface treatment process is mature, with strong anti rust and anti-corrosion capabilities, suitable for installation in outdoor or humid environments. As the flagship product of Henan Yihe Valve, this series of ventilation butterfly valves has high cost-effectiveness, sufficient stock, and fast delivery, making it an ideal choice for engineering procurement.
