| 1. | Year 2007 prasidha kendo racket made in germany , on sales now !
百希达kendo剑道球板德国制造,现已公开发售！ |
| 2. | The correct installation of ball valve and internal leak detection for gas transmission pipeline
输气管道球阀的正确安装及内泄漏检测 |
| 3. | Clean or replace gate valve with full port ball valves or resilient wedge shutoff valves
1用全流道球阀或弹性楔板关闭阀清洗或更换闸阀。 |
| 4. | Full - port ball valves provide pressure drop equal to equivalent length of pipe , and even slightly better than gate valves
不缩径，全流道球阀提供的压降安全取决于管道的长度，甚至比闸阀还要好一些。 |
| 5. | Full - port ball valves provide pressure drop equal to equivalent length of pipe , and even slightly better than gate valves
不缩径全流道球阀具有不影响整个管道压降的性能，在此方面，甚至比闸阀性能更加优异。 |
| 6. | Standard ( conventional ) port balls are up to one pipe size smaller than nominal pipe size , but still have significantly better flow than globe valves
标准（常规）流道球阀用于管道直径比管道公称通径小的管道，但是其流通能力仍然比截止阀好得多。 |
| 7. | Standard ( conventional ) port balls are up to one pipe size smaller than nominal pipe size , but still have significantly better flow than globe valves
标准(普通)流道球阀的流道直径小于管道的公称通径，但是与截止阀相比，仍然具有好的多的流动效率。 |
| 8. | Reduced port ball valves have more than one pipe size flow restriction and are not recommended in building services piping , but rather for process piping in hazardous material transfer
缩径流道球阀与单管流量相比，具有更大的限制，建议不要用于建筑领域管道，但可以用在危险材料的传输系统中。 |
