I would like to ask everyone about the issue of replacing the valve seat
Thread Content
By a replaceable valve seat, does it mean that the valve seat and the valve body are connected by threads, or is it welded on? Thank you! !
The valve seat and the valve body are not integrated; as far as I know, methods such as threaded connection and screw fixation are used.
Is it connected by welding?
Many valve manufacturers these days adopt a detachable design in their products in order to enhance competitiveness. Many components of the valves are detachable, especially those that are prone to wear and damage. This way, if there is a problem with the valve, it isn’t necessary to replace the entire valve; only the faulty components need to be replaced, which helps to reduce costs for users
There are few welded ones available on the market; to this day I haven’t seen any welded valve seats.
Some valves can be repaired or replaced. To help customers reduce costs and gain a competitive edge in the market, manufacturers design these valves to be detachable and replaceable. This post was last edited by bingyu252 on 2009-4-10 at 15:20.]
Nowadays, the seat of most valves is removable. Depending on the design of different manufacturers, the way in which the seat is connected to the valve body varies; generally, the seat is fitted over the valve body and held together by its structure, which makes it easier to install or remove. Some hard-seal seats use a ring-type structure. There are also some valve bodies that are modular in design.
\"Removable\" can be understood literally, and it also means that it can be taken apart without any damage. Connection methods such as threads and flanges are typically detachable structures. . . . . Do you think the welded structure can be disassembled intact?
I see that many specification sheets require the valve seat to be removable; it’s probably fixed by threading or bolts in most cases
