Casting B.B Globe Valve

The cast steel globe valve adopts the open rod bracket type, the bolted bonnet structure (OS&Y, BB type), the rotary lift valve stem and the hand wheel, which is an international common stop valve structure. The design of the valve body and bonnet are strictly calculated, with good strength, rigidity and circulation capacity, and meet the requirements of standard specifications. The upper cover is designed on the bonnet, which makes the packing seal more reliable in the fully open position and facilitates the replacement of the packing.
