進口法蘭全焊接球閥，全焊封鋼制球閥性能描述 Performance description

法蘭全焊接球閥（全焊封鋼制球閥）是一種很好節能環保產品，其特點在閥門關斷時內部泄漏量可達到“零泄露”狀態，可使能源流失造成的損失降低到低點。大大提高節能性與熱能計量的精確度。閥門由全焊接的閥體和碳增強特氟隆密封墊組成，可以頻繁操作，在有雜質及化學物質的情況下長壽命運行。研磨精細的不銹鋼球體可以保證多年開閉自如，運行可靠  RETZ Flanged all welded ball valve (all welded sealed ball valve) is a good energy-saving and environmental protection product. Its feature is that when the valve is turned off, the internal leakage can reach the "zero leakage" state, which can reduce the loss caused by energy loss to a low point. Greatly improve energy conservation and accuracy of heat energy measurement. The valve is composed of a fully welded valve body and a carbon reinforced Teflon gasket, which can be operated frequently and operates for a long time in the presence of impurities and chemicals. The finely ground stainless steel ball can ensure free opening and closing for many years and reliable operation
