DN50-1200 Fully-welded carbon steel ball valve with transition pipe
buried fully welded ball valve consists of fully welded body and carbon fiber reinforced seal. There are varieties of drive manual, such as manual, electric and pneumatic. Valve can be directly buried in the ground without construction of high large valve well, just set up a small shallow in the ground, greatly saving construction costs and engineering time.
