Experience in using hard-sealed butterfly valves
Thread Content
Dear experts, I am planning to use hard-sealed butterfly valves for a project; those who have used them kindly share their experience. Hard-sealed butterfly valves can withstand vacuum conditions when the medium is a solid powder. Thank you! !
Compared to soft-sealed butterfly valves, they are generally used in fluid pipelines containing solid particles. .
So if it’s for domestic use, it’s best to use a double-eccentric design; if a triple-eccentric design is required, it’s better to use imported ones!
Reply to 3# wow0011: Thank you, wow0011! !!Please recommend some domestic manufacturers of such valves. Thank you! ! !
Provide the medium, operating temperature, and other relevant parameters required by the valve.
It depends on your specific operating conditions; using imported valves provides greater stability
I have never seen hard-sealed butterfly valves used in vacuum environments.
The product quality in domestic markets cannot be guaranteed; for foreign products, one can consider the three-eccentric hard-sealed butterfly valves made by VANESSA and ORTON.
Special vacuum butterfly valves are available, designed and manufactured for vacuum environments.
