Can be used with refrigerant piping flanges! *Materials with examples are currently being provided.
Our company has extensive experience with refrigerants (such as ammonia and fluorocarbons) for manufacturers of refrigeration equipment. In some cases, we receive requests to use refrigerant pipe flanges (JIS B8602) on the opposing flange, and we have numerous examples of responding by machining grooves on the flange surface of check valves. This document includes information on "Refrigerant Pipe Flange Compatibility" and "Case Studies." Please feel free to download and review it. Additionally, we also provide compatibility for flanges used in vacuum devices on vacuum lines for vacuum pumps. *For more details, please refer to the PDF document or feel free to contact us.
