The eccentric semi ball valve has stable performance, quick and light opening, self-compensation for wear, reliable and durable sealing, easy adjustment and maintenance, straight through structure with large flow area and small damping, which can remove scale by itself, and is convenient for opening and closing. It is used to cut off, connect and adjust the medium in the pipeline.
This kind of butterfly valve has the unique advantages:
– Keeping the main valve closed and bypass valve open. That can maintain minimum flow across the valve to avoid water stagnancy and maintain water quality.
– Equalize the pressure across the valve to enable manual opening in case of power unavailability.
BFV-02-QJ Rubber lined Butterfly Valve, internally with ebonite lining of thickness 3mm or 5mm.
The typical applications of this type of butterfly valves are chemical plants, sea water treatment, desalination projects, nuclear power plants, water treatment, TSE, sewage etc.
