阀门的优点：用金属横膈膜代替人造橡胶衬垫在阀门和阀杆的顶部机件处给予了这种阀门出众的泄漏完整性。
Valve Advantages: The replacement of elastomeric packings by metal diaphragms gives this valve superior leak integrity at the top works of the valve and stem.
在此时，上阀杆已经失去了同横膈膜的接触。阀门应该开启到这一点，但不能反向固定。
At this point the upper stem has lost contact with the diaphragms. The valve should be opened to this point but not back seated.
这种损伤可能包括阀杆断裂或阻止继续使用的内部损伤。
This damage could include stem breakage or internal damage which would preclude ongoing use.
手轮可以拆卸并重新定位在环绕阀杆的六个位置中的任何一个位置上。
The handwheel can be removed and repositioned any of six positions around the stem.
非旋转阀杆防止磨损和刻痕；
阀门应该只能安装在水平流向的管线上，其阀杆应该垂直向上。如果需要其它方式的安装，请在订购阀门时咨询工厂。
Valves should be installed in the (stem) vertical position with the pipe flow horizontal only. For installations other than this, please consult factory when ordering.
从阀杆上拆卸手柄，向上提升并将手柄从阀体上取出。
Remove the handle from the stem by pulling upward and away from the body.
阀杆也应该在顶部配置方向指示器，用于当手柄拆卸下来时指示阀瓣的位置。
The shaft also shall have a directional indicator on top to indicate disc position when the handle is removed.
在人工手动操作阀杆时，如果水路畅通，热水会排泄出来。
When the lever is operated, Hot water will discharge if the waterways are clear.
阀杆应该是以镀镉钢合金或316不锈钢作为标准配置。备选的阀杆材料可以根据要求提供，例如，钛，不锈钢，等等。
The shaft shall be cadmium-plated steel alloy or 316 stainless steel as standard equipment. Optional shaft materials shall be available on request, i. e. , titanium, stainless steel, etc.
阀盖轴承和整体阀座轴承引导阀杆总成，实现与阀座的精确定位。
A cover bearing and integral seat bearing guide the stem assembly for precise alignment with the seat.
阀杆应该是六角形或方形，以确保阀瓣能够灵活旋转，并且完全密封，不会暴露在处理的液体里。
The shaft shall be hexagonal or square to ensure positive rotation of the disc and be totally sealed from exposure to the process liquid.
压力的变化将精确定位阀杆总成，使得阀门实现所要求的启、闭或调节的操作。
Varying the amount of pressure accurately positions the stem assembly to open, close or modulate the valve as required.
当上阀杆沿着它的螺纹上下运动时，通过机械连接带着下阀杆一起运动。
When the upper stem rides up and down on its threads it now moves the lower stem by a mechanical connection.
阀杆的螺纹尾部始终在填料之上，防止运动时带出填料。
Stem the screw on the rear always fill in, to prevent the movement with filler.
精密加工的阀杆和填料腔。
上阀杆通过丝口旋在横膈膜止动螺母里。
阀杆和填料密封装置同样采用不锈钢，具有耐腐蚀性能。
The stem and packing gland are also stainless steel for corrosion protection.
