Does that technician know what this one-way valve is?
Thread Content
The material list specifies a flanged ball check valve – is there a model number? Asked the experts for help, thanks!
It seems to be a lift-type check valve with springs.
It’s rare to see it in terms of its appearance; it’s probably not a conventional lift-type or swing-type valve. There are likely springs involved, but it’s hard to say exactly what the internal structure is like. Nothing similar was found in the valve manual; if possible, check the model number, or simply and directly find an identical one to take apart and examine.
Inside are one-way valves similar to compressor valves!
If it has a spring, it should be installed vertically; otherwise the valve core will shift, which affects the check function!
It should be spring-type. What was said on the 5th floor about the need for vertical installation isn’t necessarily true. From the picture, it seems to be installed horizontally.
It looks like a flanged ball valve, but I don’t see any actuator or handle or other control devices
H44 swing check valve, installed horizontally.
Spherical check valve, model H40, with a ball inside that can move up and down
The day before yesterday, I asked someone and was told that the model is H40F46-16. I also measured the connection dimensions of this valve manually; they are 195 mm. Factories and mines here rarely use this type of check valve – it’s a valve used in environmental protection equipment! Thank you to all the experts upstairs!
