DiscValves that move along the centerline of the seat are called globe valves. We judge the movement form of the valve disc, the change of the valve seat port and the valve disc stroke are in direct proportion.
Forged steel globe valves have three body-cover connection designs:
1. Forged steel globe valve with body cover welded connection, the valve designed according to this connection form, the valve body and the valve cover are fully welded and sealed, and the advantage is that there is no external leakage.
2. It is a pressure self-tightening bonnet forged steel globe valve. For the valve designed according to this connection form, the valve body and the bonnet are connected by screws, and the internal pressure is self-sealing ring. The advantage is that the greater the internal pressure, the tighter the seal. The better the performance.
3. It is a forged steel globe valve connected by bolts on the body cover. The valve designed according to this connection form, the valve body and the valve cover are connected by bolts, and the wound gasket is sealed. The advantage is that it is easy to maintain.
After reading the above content, you must have a deep understanding of the advantages and connection forms of forged steel globe valves, thenYou can choose the valve reasonably according to the actual working conditions.
