鍛鋼截止閥產品概述
鍛鋼截止閥系列產品是按照API602進行設計的高壓截止閥,閥體和閥蓋為A105、F22、F11、C5、F304、F316、F321等材料整體鍛造而成,閥體閥蓋通過螺栓連連接,按照連接方式不同分為法蘭鍛鋼截止閥、螺紋鍛鋼截止閥和焊接鍛鋼截止閥,壓力等級為:Class150-Class2500,公稱通徑:1/4-2″。廣泛應用于石油化工、電力、化工的裝置和管路。
鍛鋼截止閥產品特點
1、閥門采用模鍛工藝、結構緊湊、造型美觀、縮徑流道。閥體閥蓋采用明桿支架螺栓連接。
2、密封面可根據使用的工況選擇Cr13不銹鋼、STL硬質合金。填料可選擇柔性石墨或者PTFE。
3、閥瓣為圓錐形,閥桿設有倒密封,密封性好。閥桿表面經氮化處理,具有良好的抗腐蝕性、抗摩擦性。密封可靠,操作靈活,啟閉力矩小。
4、可選用各種配管標準及連接形式(如:承插焊、對焊、螺紋連接)。
