订货示例,在基本型号后添加通道机能形式代码,如:BK3 G1/4 06 1125 L 注意!!
|
BK3/SK3标准球阀的密封功能只在以下两种情况下有效: 1. 被关闭的接口压力为零; 2. 两个连通接口的压力高于被关闭接口的压力; 如果要求所有接口都受压(PN1=PN2),或用于气体介质的三通球阀,则是另一种特殊密封结构的三通球阀,订货时需在型号后加 "A" 。 |
球阀钢球通道机能形式:
中间位置(90°时)只能中间接口承受压力。
阀体尺寸以及工作压力,适用于各种接口形式
(PEEK:聚醚醚酮密封,具有较好耐腐蚀性; POM:聚甲醛密封; PTFE增强聚四氟乙烯密封,具有极好耐腐蚀性)
