Service and Replacement Parts
不需要从管道上拆卸阀门，就可以对内部部件进行拆卸、维修或检查。
Internal parts can be removed, repaired or inspected
without removing the valve from the piping.
拆卸
Disassembly:
- 关闭供应压力和排泄阀门。

Remove the two hood screws, remove hood.
- 反时针方向旋转拆卸阀盖螺丝。

To assist with removal a small flow can be applied by "cracking" the
inlet valve slightly.
重新装配
Reassembly:
通过将固定器内的U形剪切块和阀门出口对齐来将新固定器模块总成安装到阀体内。固定器的顶部必须刚好位于阀体内螺纹下方。按照相反步骤重新组装剩下的部件。
警告：如果隔膜断裂，则可能产生泄漏或溢出。在组装期间必须要小心谨慎，不要损坏部件。
Install new retainer module assembly into valve
body by aligning "U" shaped cutout in retainer with the valve outlet.
The top of retainer must drop just below threads in the valve body. Reassemble
