一、J41H法兰截止阀主要用途:
法兰截止阀,不锈钢法兰截止阀,J41H铸钢截止阀适用于公称压力PN1.6~16MPa,工作温度0~425℃的石油、化工、制药、化肥、电力行业等工况的管路上,切断或接通管路介质。驱动方式有手动、齿轮传动、电动、气动等。J41H铸钢法兰截止阀的启闭件是圆柱形的阀瓣,密封面呈平面或锥面,阀瓣沿流体的中心线作直线运动。国标截止阀只适用于全开和全关,一般不用来调节流量,定做时允许作调节和节流。型号: J41H-16C(铸钢)、J41H-16P(304)、J41H-16R(316)、J41H-25C、J41H-40C、J41H-64C、J41H-64P、J41H-64R
二、J41H铸钢法兰截止阀产品特点:
1、结构简单,制造和维修比较方便
2、工作行程小,启闭时间短
3、密封性好,密封面间磨擦力小,较长
