当阀门内出现污垢和堆积物，或在防回流阀内出现机械故障，则可能会产生安全阀排放。美国瓦茨113-6RFP系统能够防止由于这种排放造成的财产损失。能够造成安全阀持续排放的典型条件是：减压防回流阀的第一止回阀阀座上的污垢或堆积物，安全阀感应线被堵塞，安全阀隔膜故障，第一止回阀弹簧断裂。
　　The Watts 113-6RFP system prevents property damage due to relief valve discharge that can occur due to dirt and debris within the valve or a mechanical failure within the backflow prevention assembly. Typical conditions which can cause continuous relief valve discharge are: dirt/debris on first check seat of the reduced pressure backflow preventer, clogged relief valve sensing line, relief valve diaphragm failure and broken first check valve spring.
　　美国瓦茨113-6RPF控制阀在正常情况下保持全开位置。如果减压区（RPZ）安全阀开启，则穿过排泄管的超额流量将触发流量感应器，从而激发113-6RFP阀门上的电磁阀，从而实现113-6RFP阀门的关闭。与普通电磁阀不同，当流量停止或者电磁阀没有被激发时，113-6RFP无法重新开启。对于间歇流量，美国瓦茨的解决方案是配置一个位于流量感应器和113-6RFP之间的JB113接线盒里的延时装置，用于防止控制阀上的电磁阀在不需要时被激发。要提供安装型号51限制开关的阀门，用于传送一个远程信号至声响警报器，表示阀门已经关闭。在建筑维护工程师或防回流技术人员维修了减压区（RPZ）后，可以用113-6RFP配置的手动重置装置恢复流量。
　　The Watts 113-6RFP control valve remains fully open under normal conditions. If the RPZ relief valve should open, excess flow through the drain pipe trips the flow sensor which energizes the solenoid on the 113-6RFP valve and it goes closed. Unlike a normal solenoid valve, the 113-6RFP cannot re-open if flow stops and/or the solenoid is deenergized. The Watts solution to intermittent dumping is a time delay located in the JB113 Junction Box between the flow sensor and the 113-6RFP to keep the control valve solenoid from energizing until required. A valve mounted Fig. 51 Limit Switch is supplied which sends out a remote signal to sound an alarm, indicating that the valve is closed. The 113-6RFP is equipped with manual reset to restore flow after the RPZ is repaired by the building maintenance engineer or backflow technician.
　　113-6FRP堵漏阀配置JB113接线盒，型号51限制开关，以及FS99流量感应器。FS99流量感应器精确感应排泄管道内的水流。113-6FRP也能够连接到流量开关或多种类型的浮动开关上。请咨询美国瓦茨代表了解相关的兼容性。
　　The 113-6FRP Flood Protection Valve comes complete with a valve mounted JB113 Junction Box. Fig. 51 Limit Switch, and FS99 Flow Sensor. The FS99 Flow Sensor accurately senses water flow in the drain pipe. The 113-6FRP can also be connected to a Flow Switch or various types of Float switches. Consult your Watts Representative for compatibility.
　　如果主阀门和引导隔膜用坏，则美国瓦茨ACV 113-6RFP完全能够实现故障安全关闭。这种阀门配置一个压力表和一个手动操作机构，可用于定期检测。主阀配置防锈阀杆，用于防止阀门长期没有检测所出现的故障。
　　The Watts ACV 113-6RFP is totally fail safe for closure if the main valve and pilot diaphragms wear out. It is equipped with a gauge and a manual operator for periodic testing. The main valve has an anti-scale stem for protection if the valve is not tested for long periods of time.
