訂貨示例,在基本型號后添加通道機(jī)能形式代碼,如:BK3 G1/4 06 1125 L 注意!!
|
BK3/SK3標(biāo)準(zhǔn)球閥的密封功能只在以下兩種情況下有效: 1. 被關(guān)閉的接口壓力為零; 2. 兩個連通接口的壓力高于被關(guān)閉接口的壓力; 如果要求所有接口都受壓(PN1=PN2),或用于氣體介質(zhì)的三通球閥,則是另一種特殊密封結(jié)構(gòu)的三通球閥,訂貨時需在型號后加 "A" 。 |
球閥鋼球通道機(jī)能形式:
中間位置(90°時)只能中間接口承受壓力。
閥體尺寸以及工作壓力,適用于各種接口形式
(PEEK:聚醚醚酮密封,具有較好耐腐蝕性; POM:聚甲醛密封; PTFE增強(qiáng)聚四氟乙烯密封,具有極好耐腐蝕性)
