It is recommended not to get stuck on the name; focus on understanding the functions, learning how to use them correctly, and being good at analyzing faults for repairs
In China, it is generally called a sleeve valve, while abroad it is referred to as a cage valve – the structural principle remains the same; only the name differs.
Single-seater ones come with cages and those without cages. Single-seat with a cage; the valve seat can be removed and replaced, while the valve seat of those without a cage cannot be replaced. The sleeve must be equipped with a cage, but the valve seat can be replaced or not.
