j41y/j40h大口径美标截止阀的阀体采用球形结构，造型美观，阀座阀瓣采用锥形密封结构，密封可靠。美标法兰截止阀适用于Class150～2500，工作温度 29～425℃（美标铸钢截止阀）或 -196～600℃(不锈钢美标截止阀)的各种管路上，用于截断或接通管路中的介质。用于截断或接通管路中的介质，选用不同的材质，可分别适用于水、蒸汽、油品、硝酸、醋酸、氧化性介质、尿素等多种介质。
   j41y/j40h大口径美标截止阀产品特点http://www.zk-v.com/ProductShow_355.html
1、阀体外形为球形或流线形造型美观。流通形状为直通式，流体阻力小。
2、阀瓣和阀座密封副采用锥面密封，密封可靠，杂物不易落在密封面上，关闭力小，耐冲刷，密封可靠，
3、阀座可为更换式阀座，可任意组合与关闭密封面材料的配对，以满足工况的要求，延长使用寿命。
4、大口径、高压力截止阀根据关闭力的需要阀杆的传动方式采用升降杆，并配有滚动轴承式采用伞齿轮以减轻关闭力。
5、阀体、阀瓣、阀杆、填料、紧固件的材料可按实际工况要求合理选配，以适用于多种不同的工况环境。
