Product Description
The split bolt connection fixed ball valve is anopen-close type control valve. The valve adopts side-mounted split boltconnection, usually adopts two-piece or three-piece structure design, conformsto API6D standard, and the seat sealing structure adopts multi-stage sealing(patent) technology. The valve has double blocking and venting function, andThere is a secondary emergency seal grease structure design to ensure leakagefrom the valve seat and stem. This series of valves has higher reliability,tightness, higher strength and longer service life. , It mainly used in naturalgas and transportation systems.
