Stainless steel gate valve seat: body Seat or welded seat
The valve seat of stainless steel gate valve has both body seat and welded seat.
1、 Seat type of válvula de compuerta de acero inoxidable
The seat types of stainless steel gate valves usually include two types: body seat and welded seat. Among them, the main valve seat refers to the valve body itself being the valve seat, while the welded valve seat refers to the valve seat and valve body being manufactured separately and then welded.
2、 Advantages and disadvantages of the main valve seat
1. Advantages:
The advantage of the main valve seat is that it has a lower manufacturing cost and is less prone to leakage. In addition, due to its integrated manufacturing with the valve body, the body valve seat can greatly reduce the rotational inertia of the valve, improve the opening and closing speed of the valve, and thus enhance the operational efficiency of stainless steel gate valves.
2. Disadvantages:
The disadvantage of the main valve seat is that due to the integrated manufacturing of the valve seat and body, the anti-corrosion ability of the valve is poor. Meanwhile, due to the selection of valve body materials, the scope of application of the valve will also be limited to a certain extent.
3、 Advantages and disadvantages of welded valve seats
1. Advantages:
The advantage of welding the valve seat is that, due to the separate manufacturing of the valve seat and body, different materials can be used to make the valve have higher corrosion resistance. Meanwhile, the welded valve seat can also be made of composite materials to improve the service life of the valve.
2. Disadvantages:
The disadvantage of welding valve seats is that they have high manufacturing costs and are prone to leakage points. Due to the complex socket welding process required for the manufacturing of welded valve seats, a high level of technical expertise and production technology is also needed.
4、 Summary
The valve seat of stainless steel gate valve has both body seat and welded seat. Both have their own advantages and disadvantages, which need to be selected according to specific usage requirements and situations. It is worth noting that when purchasing and using stainless steel gate valves, it is necessary to choose valve products with good quality and reliability to ensure the normal operation and safe functioning of the valve.
