If a valve is labeled as a stainless steel ball valve, is it made entirely of stainless steel, or is only the valve body made of stainless steel? The pipes are made of stainless steel.
Where to mark? The model is marked with P, indicating that the valve body is made of stainless steel. Generally, the valve body is indeed made of stainless steel, and the internal components are also of a material no less durable than that of the valve body, meaning stainless steel as well; thus, the entire valve is made of stainless steel. Of course, the non-metallic seals such as valve seats inside may be made of rubber or plastic.
Looking at the model, Q41F indicates a soft seal, while Q41H denotes a hard seal; there are also models such as Q41Y and Q41W
Check the model designation; it indicates the materials of the sealing surface and the valve body
For the sealing of the valve core and valve stem, there should be separate options available, right?
For a full stainless steel ball valve, the model should be Q41W-16P/25P/64P, etc., or PL, R, RL, etc. The stainless steel materials used for valves include: 304 stainless steel, 304L stainless steel, 316 stainless steel, 316L stainless steel, and others.
Commonly known as stainless steel valves, their main material is definitely stainless steel, with only a few sealing components used
