又来请大神翻译一下，取取经！！

Thank you. A couple of questions: 1.? ?? ?Do you he the capability to test your 6000psi ball valves under pressure to 6000psi? I notice you only do a standard hydrostatic test at 80 – 100 psi, which does not confirm the valve’s ability to hold 6000psi. 2.? ?? ?Change the seat configuration to Delrin seats instead of peek, as there is not high temperature involved, and peek seats tend to be a bit harder. 3.? ?? ?30 days to ship China is fine. If I need them sooner I will advise you. 4.? ?? ?Most importantly, since the drawing only shows standard ID??dimensions on the ends, please confirm that you will bore the ID of the valve ends to the stated ID bore on the purchase order. The balls do NOT need to be bored to the same ID as the ends. Standard full port balls are required to facilitate zero pressure drop through the valve. 我该怎么回答好，6000的产品，就是我们的特色产品，求大神给个范本，我想回答的更专业，总是中文式翻译让人很无奈！！！
