闸阀 美国A＆N公司 高真空阀门

Gate valves provide straight-through, unimpeded flow with the smallest valve body profile.闸阀提供直通式，畅通，与阀体zui小的个人资料。 Gate valves are ideal for space-constrained applications that require maximum conductance.闸阀是zui大电导为空间受限的应用中的理想选择。 A&N gate valves are available in sizes ranging from 1.5 to 12 inches （nominal ID）. A＆N闸阀尺寸范围从1.5到12英寸（标称ID）。 Port terminations are available in three flange families （ISO, CF, and ASA）.接口端可在三个的法兰家庭（ISO，CF，和ASA）。 Manual and pneumatic actuators are available for all A&N gate valves.手动，气动执行器适用于所有A＆N闸阀。 For ultra-high vacuum applications, a copper bonnet seal version （with CF port terminations） is also available.对于超高真空应用，铜阀帽密封版本（CF接口端）也是可用的。 Principles of Operation and Construction: A central carriage or gate is raised and lowered by the actuator within the body.*马车的构造和操作原则：A或门提高，降低身体内的执行机构。 In the open position the gate retracts compley from the tube aperture allowing unrestricted flow.在打开位置上的栅极从管孔径*缩回允许不受限制地流动。 In the closed position an elastomer sealing ring is compressed against the surface on the inside of one of the body ports.在关闭位置时，被压缩的弹性体密封环反对身体端口之一的内部的表面上。
