The sealing characteristics are similar to a flanged diaphragm valve, a large flow.
The valve body can be removed from the pipe in bv loosening the union nuts at both 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.
