进口法兰全焊接球阀 天然气燃气全焊封球阀 美国RETZ瑞茨

　　品牌：retz瑞茨/我们一直致力于流体控制领域的持续创新，始于2005……进口法兰全焊接球阀不需要维护，在低运行费用下长期可靠运行。不会有外部泄漏等现象。阀体是焊接结构，所以阀门重量轻且易于进行绝缘thefully welded flange ball valve does not require maintenance and can operatereliably for a long time at low operating costs. there will be no externalleakage or other phenomena. the valve body is a welded structure, making itlightweight and easy to insulate

　　进口法兰全焊接球阀 天然气燃气全焊封球阀性能描述 performancedeion

　　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，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jing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 (allwelded sealed ball valve) is a good energy-saving and environmental protectionproduct. its feature is that when the valve is turned off, the internal leakagecan reach the "zero leakage" state, which can reduce the loss causedby energy loss to a low point. greatly improve energy conservation and accuracyof heat energy measurement. the valve is composed of a fully welded valve bodyand a carbon reinforced teflon gasket, which can be operated frequently andoperates for a long time in the presence of impurities and chemicals. thefinely ground stainless steel ball can ensure free opening and closing for manyyears and reliable operation
