What are the standards for angle valves?
Thread Content
As the title suggests, under conditions conducive to crystallization, what are the standards for angle valves used for bottom discharge or pipeline discharge (those with a saddle-shaped valve core that is level with the inner wall of the container or pipeline)?

There aren’t many domestic manufacturers producing it. We’ve used products from the 11th Academy of Aerospace Science and Technology, as well as imported products from Japan; both performed quite well. It seems there’s no unified standard for this product in China, right? I’m not sure if it’s the same valve as the one mentioned by the original poster.
HG T 3218-2016 Bottom-opening discharge valve with gasket; HG T 3217-2016 Top-opening discharge valve with gasket; JB T 450-2008 Technical specifications for forged angular high-pressure valves – depend on the specific application
