Ventilation butterfly valve is a non sealed butterfly valve suitable for pipelines with medium temperature of 300 ℃ and nominal pressure of 0.1Mpa in production processes such as building materials, metallurgy, mining, and electricity. It serves as a pipeline control device for regulating flow or cutting off gas medium
Ventilation Butterfly ValveIt is a non sealed butterfly valve suitable for production processes such as building materials, metallurgy, mining, and electricity, with medium temperatures ≤ 300 ° C℃On a pipeline with a nominal pressure of 0.1Mpa, it serves as a pipeline control device for regulating the flow rate or cutting off gas media.
Ventilation butterfly valves are divided into manual and electric transmission, which can be driven by an electric motor or turbine to drive the actuator, allowing the butterfly plate to rotate freely within a 90 ° range to achieve the purpose of opening and closing or adjusting the medium flow rate.
Universal butterfly valveStructural points:
1. Designed and manufactured using a new structural form of welding midline disc plates and short structural steel plates, it has a compact structure, light weight, easy installation, low flow resistance, large flow capacity, avoids the influence of high temperature expansion, and is easy to operate.
2. There are no connecting rods, bolts, etc. inside, and the working and service life is long. Can be installed in multiple workstations without being affected by the flow direction of the medium
