Features：
● The sealing characteristics is similar to flanged diaphragm valve, large flow.
● The valve body can be removed from the pipe line by loosening the union nuts at both its ends.
● Existing cases show that due to factors such as installation errors in factory pipelines, it is easy to cause the union nut to be overstressed and leak or even be damaged. Therefore, it is not recommended to use a valve with a union connection structure above DN50.
