Stop Valve Seat
1. The structure of Stop Valve Seat is simpler than that of gate valve, and it is more convenient to manufacture and maintain.
2. The sealing surface of the Stop Valve Seat is not easy to wear and scratch.
3. The Stop Valve Seat has better sealing performance and longer service life.
4. Stop Valve Seat has small working stroke and short opening and closing time.
- Information
Introduction of Stop Valve Seat:
Stop valve refers to a valve in which the closing member (disc) moves along the centerline of the valve seat. According to the movement form of the disc, the change of the port of the valve seat is proportional to the stroke of the disc. Since the opening or closing stroke of the cut-off valve stem is relatively short, and it has a very reliable cut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for flow adjustment. Therefore, the Stop Valve Seat is very suitable for cutting or adjusting and throttling.
Application scenarios of Stop valve seat:
Stop valve seat is very suitable for frequent switching needs and can be used in most media flow systems. Globe valve seats are widely used in petrochemical, electrical, metallurgy, urban construction, chemical and other industries.
The main advantages of the Stop valve seat:
1. When fully open, the disc is often eroded. The stem axis of Valve casting is perpendicular to the sealing surface of the valve seat. The opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off action, making this valve suitable for cutting or regulating and throttling the medium.
2. There is no fluid loss and energy loss is reduced. Valve casting can improve the safety of factory equipment.
3. Since the flow direction of the medium through the valve has changed, the minimum flow resistance of the Stop valve seat is also higher than that of most other types of valves.
4. Usually there is only one sealing surface on the valve body and the valve disc, so the manufacturing process is relatively good and it is easy to maintain.
