Filter valve is a product manufactured through high-temperature casting technology for civil air defense engineering pipeline cut-off or regulating cut-off. It has certain characteristics such as low flow resistance, easy opening and closing, corrosion resistance, and wide application. It is widely used in automatic sprinkler systems, water supply and drainage pipelines, fire hydrant water supply systems, etc., to improve work efficiency and ensure people's lives.
Filter valves are mainly composed of ductile iron valve bodies, copper valve stems, and ductile iron special handwheels. Filter valves are mainly used in fields or scenarios such as automatic sprinkler systems, water supply and drainage pipelines, and fire hydrant water supply systems. The use of filter valves in automatic sprinkler systems can prevent pipeline water flow from not being quickly cut off. In water supply and drainage pipeline scenarios, it can prevent damage to pipelines caused by excessive water pressure when water regulation changes direction. In fire hydrant water supply system scenarios, it can prevent the medium in the pipeline from not being quickly redirected during maintenance and causing backflow.
