美标法兰截止阀


J41H、J41Y、J41W API美标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。


【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,寿命较长。

Product Application Scope

These devices are suitable for accurately controlling media such as gases, liquids, steam, etc., and maintaining process parameters such as pressure, flow rate, temperature, and liquid level at given values. Especially suitable for work environments where the allowable pressure difference is small and the allowable leakage is also small, and the pressure difference is not significant.
