Electric Ash Discharge Ball Valve

Electric Ash Discharge Ball Valves are used in ash discharge pipelines across metallurgy, building materials, power generation, and other industries. Featuring an imported sealed structure, they operate smoothly without ash accumulation and offer reliable sealing performance. Available drive options include manual, pneumatic, hydraulic, and electric actuation. Suitable for fine-grained powdered media such as blast furnace gas ash and cement, with an operating temperature rating of ≤250°C.
