Eccentric hemispherical control valve
Thread Content
What are the features and advantages of eccentric hemispherical control valves? Can it be used to regulate the flow rate of dust-containing oil products?
The biggest advantage is that there is no issue of sediment accumulation in the valve chamber, allowing it to be used for rough regulation of oil products containing dust
As mentioned above, it prevents sediment buildup in the valve’s interior cavity, and can be used for rough adjustment of oil products containing dust.
When activated, the sealing surfaces separate instantly, resulting in a large flow area and making it difficult for the medium to erode the valve body.
Its features include low torque and easy operation; it is suitable for applications with large pressure differences. However, many eccentric hemispherical valves still have a ball valve-style seat structure, which makes it easy for impurities to accumulate in the seat spring chamber, leading to the seat getting stuck.
