Personally, it is recommended not to supply valves that meet US standard requirements under the corresponding national standard models. I guess (for reference only): V-valve ； Q-ball valve ； R-RF plane ； 2-150Lb ； A-Valve body material, such as carbon steel ； D-Internal component material and sealing surface, such as stainless steel 304 + hardened treatment ； 11-Special requirements for valves ； C-band drive mechanism. The valve body is made of carbon steel, while the internal components are made of stainless steel and have been hardened. The diameter is large enough, which is why a driving mechanism is provided. 11 likely implies special requirements for the valve; it may be used with media containing solid particles, and a scraper design is required, among other things.
