- 产品名称:J41H铸钢法兰截止阀
- 简要描述:
一、J41H法兰铸钢截止阀主要用途：
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、电力行业等各种工况的管路上，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
