Recently I went to see the transformation of the factory look, now replaced by Triple offset butterfly valve, and so the better. Before all the old valve, it is really difficult to use, and the new Triple offset butterfly valve operation is easy, for our factory workers, it is good news, usually the valve opened and closed often, the quality is not good on easily broken, and difficult to operate, it is really troublesome, now replaced Triple offset butterfly valve, it usually is easy to operate and not easily broken, everything really, of course, a good new factory to transform the course to change the more the better.
