無間隙刀閘閥是利用兩橡膠閥座對夾壓緊閘板起到密封效果，當閘板*開啟時，兩密封閥座相靠緊，加上管道內壓使得密封效果更好，同時閥門關閉時，閘板可以隨意方便的拆下維修，不需要拆下整個閥門進行維修而影響管道正常運作。此閥門主要特點是通徑全橡膠密封閥座，具有很強抗磨損特性和全通徑流通性。適合于那些要求閥門耐磨的工礦管道上使用。

No gap knife gate valve makes use of two rubber seats to pressure clipping to achieve gate sealing effect. Two sealed valve connected together when gate is opened completed. When gate is closed , gate not all the valve, can be taken down to mend . The main feature of this kind valve is entire rubber seal of diameter with anti-wear properties and all-pass runoff common gender .It's suitable for industrial and mining pipe that need valve well resistant.
