1. 在握住阀盖时拆卸四个或六个安全阀阀盖螺栓。
   Remove the four or six relief valve cover bolts while holding the cover down.
2. 将阀盖直接提起。阀杆和隔膜总成通常随着阀盖一起拆卸。安全阀弹簧此时留在阀体内。
   Lift the cover straight off. The stem and diaphragm assembly will normally remain with the cover as it is removed. The relief valve spring will be free inside the body at this point.
3. 安全阀阀座位于阀体镗孔底部，如果必要的话，可以被拆卸进行清洗。不需要拆卸安全阀模块也可以清洗阀瓣。如果确定安全阀隔膜和/或阀瓣应该被更换，则不需要使用特殊工具就可以拆卸安全阀模块。
   注： 阀瓣橡胶模制在阀瓣固定器内，作为阀瓣固定器总成提供。
   The relief valve seat is located at the bottom of the body bore, and can be removed, if necessary, for cleaning. The disc can be cleaned without disassembly of the relief valve module. If it is determined that the relief valve diaphragm and/or disc should be replaced, the relief valve module can be readily disassembled without the use of special tools.
   Note: The disc rubber is molded into the disc holder and is supplied as a disc holder assembly.
4. 为了重新装配安全阀，要把阀座牢牢地压在阀体内，将弹簧放置在阀座上的中心位置，将阀盖和安全阀模块作为一个整体直接插入到镗孔内。压住阀盖，确保适当的对齐。插入和紧固螺栓。
   警告：如果阀盖没有压平在阀体上，阀杆总成将可能扭曲和损坏。在插入螺栓之前重新对齐阀杆和阀盖。
   注： 不需要特殊工具即可维修系列009通径DN65 - DN80。
   To reassemble the relief valve, press the seat firmly into place in the body, center the spring on the seat, and insert the cover and relief valve module as a unit straight into the bore. Press down on the cover to assure proper alignment. Insert and tighten bolts.
   Caution: If cover will not press flat against body, stem assembly is crooked and damage can result. Realign stem and cover before bolts are inserted.
