Recently our factory to employees on holiday, this is a rare case of the year before it. In addition to our factory never let go the extra holidays to employees a day off, the holiday is also a reason. The reason is that our factory Triple offset the pipelines on the butterfly valve used for long years, and some of the need to replace aging, so give our employees put a few days off. Factory pipeline Triple offset butterfly valve since the plant opened up to now has not been replaced, really durable replacement now because time is too long, to the future without affecting the normal operation, so busy these days to take advantage of the factory to be replaced.
