　　用在泵系统上，保护设备不会受到由于管线内流量变化而产生的压力波动或起伏的破坏。116-52通过开启预置低压设置点来做出响应，使其迅速释放返回的高压波。当整个蓄压装置在排放时阀门保持在开启状态，然后才关闭。这样就防止可能出现的系统过度排放，以至于压力无法恢复到低压设置点及以上。还可以配置一个高压控制器，以便于进行高压释放。
　　Used in pumping systems to protect equipment from damaging pressure surges or waves caused by rapid changes of flow within the pipeline. The 116-52 responds by opening at a preset low pressure setting, allowing for quick relief of the returning high pressure wave. The valve remains open as the integral accumulator is charged and then closes. This prevents possible excess system drainage should pressure not return to/above the low pressure setting. It is also equipped with a high pressure control pilot which allows for high pressure relief service.

　　注：
　　调节范围：
　　低压：标准为20-200 psig，选项为0-30 psig
　　高压：标准为20-200 psig，选项为0-30，100-300 psig
　　NOTE:
　　Adjustment range:
　　Low pressure: standard 20-200 psig, optional 0-30 psig.
　　High pressure: standard 20-200 psig, optional 0-30, 100-300 psig

　　快速选型：阀门通径比主管线通径小一到二级。
　　QUICK SIZING: Valve size one or two sizes smaller than main line.
