Stop valve SHJ41W-16PDN50
Thread Content
Is there such a designation for the globe valve SHJ41W-16PDN50?
JB/T 308-2004 \"Valves – Method for Naming Models\" provides detailed regulations.
Some depend on the manufacturer’s code, while others do not follow standards.
SHJ seems to be a handwheel mechanism used in conjunction with a piston actuator; it is described on http://www.kvcv.com/Shop/ShowProduct.asp?ProductID=87, where 41 indicates the connection method and the threading style； W indicates that all the secondary materials of the valve are made from the same material as the main body; what follows is the nominal pressure. This is how I understand it
It can be labeled this way; as long as the main letter codes meet the standard requirements.
These are probably again some weird tricks from the design institute
Manufacturers can also easily add a prefix based on their company’s abbreviation
The part at the front is the manufacturer’s logo; it was copied directly from the manufacturer’s valve catalog during the design process
J41H-16P and DN are both correct. SH may be the manufacturer’s code.
It is usually represented as J41W-16PDN50; I have never seen a version with SH
