j41y/j40h大口徑美標截止閥的閥體采用球形結構，造型美觀，閥座閥瓣采用錐形密封結構，密封可靠。美標法蘭截止閥適用于Class150～2500，工作溫度 29～425℃（美標鑄鋼截止閥）或 -196～600℃(不銹鋼美標截止閥)的各種管路上，用于截斷或接通管路中的介質。用于截斷或接通管路中的介質，選用不同的材質，可分別適用于水、蒸汽、油品、硝酸、醋酸、氧化性介質、尿素等多種介質。
   j41y/j40h大口徑美標截止閥產品特點
1、閥體外形為球形或流線形造型美觀。流通形狀為直通式，流體阻力小。
2、閥瓣和閥座密封副采用錐面密封，密封可靠，雜物不易落在密封面上，關閉力小，耐沖刷，密封可靠，
3、閥座可為更換式閥座，可任意組合與關閉密封面材料的配對，以滿足工況的要求，延長使用壽命。
4、大口徑、高壓力截止閥根據關閉力的需要閥桿的傳動方式采用升降桿，并配有滾動軸承式采用傘齒輪以減輕關閉力。
5、閥體、閥瓣、閥桿、填料、緊固件的材料可按實際工況要求合理選配，以適用于多種不同的工況環境。
