J41W不銹鋼截止閥產品說明
J41W不銹鋼截止閥的啟閉件是閥瓣，閥瓣的運動方向與流體方向相垂直，截止閥只能作全開和全關 , 如作調節(jié)和節(jié)流作用，需要更換閥瓣。閥體、閥蓋、閥瓣、閘桿使用不銹鋼材料，材質有CF8，CF3，CF8M,CF3M等，閥座密封面為聚四氟乙烯、不銹鋼+硬質合金或堆焊硬質合金，填料一般采用硬質合金、聚四氟乙烯、石棉石墨或柔性石墨。公稱尺寸 DN15~DN800，工作壓力 1.6MPa~20.0MPa，適用溫度 ≤200℃，適用于硝酸類、弱腐蝕性介質管路中。
J41W不銹鋼截止閥產品特點
- 采用奧氏體不銹鋼，對氧化性酸介質擁有良好的耐蝕性。
- 介質流經不銹截止閥時不改變其流動方向，流體阻力小。
- 閥瓣運動方向與介質流動方向相垂直，啟閉力矩小，開閉較省力。
- 閥瓣垂直置于閥體內，結構長度較短。
- 密封性能好。全開時密封面受沖蝕較小。
