供应 Pacific闸阀

闸阀是当今工业中**常用的切断阀。 

它们使用在需要**小压降和双向切断的场合。闸阀不能用于节流工况。在阀位部分开启的情况下长时间使用，常常会损伤阀座表面。闸阀可以配置多种结构型式的楔形阀板（实心、弹性和分体），以更好地满足特定的工况条件。

闸阀通常是手轮操作，但也提供齿轮箱、电动执行机构，或气缸（气动或液压）执行机构以实现远程操作。

Pacific wedgeplug valves are chosen for delayed coker isolation where the service is not only high temperature, but also presents other valve designs with seating issues when decoking 

occurs. Because of wedgeplug's unique seating arrangement where the seats are protected from the media in both the seated open and seated closed position, along with the purging options during the opening and closing cycles, there is no other valve with the design and experience combination to handle severe services.
