美国采购需求：静音空气压缩机，便携式空气压缩机，1HP空气压缩机，无油空气压缩机，1加仑罐式压缩机，LG2100空气压缩机

I'm looking for a replacement check valve for my 1hp air compressor. Unfortunately, the original part has broken, and I need to find a suitable replacement as soon as possible. Could you please let me know where I can purchase a new check valve? If you have any recommendations or specific suppliers, I'd greatly appreciate your guidance. Thank you for your help!
