法兰全焊接球阀 全焊封钢制球阀

进口法兰全焊接球阀，全焊封钢制球阀性能描述 Performance description

法兰全焊接球阀（全焊封钢制球阀）是一种很好节能环保产品，其特点在阀门关断时内部泄漏量可达到“零泄露”状态，可使能源流失造成的损失降低到低点。大大提高节能性与热能计量的精确度。阀门由全焊接的阀体和碳增强特氟隆密封垫组成，可以频繁操作，在有杂质及化学物质的情况下长寿命运行。研磨精细的不锈钢球体可以保证多年开闭自如，运行可靠  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
