Design FeaturesDesign features

● Provides a pressure differential on both sides of the back pressure valve piping

● Prevents siphoning, Eliminates dosing variations caused by pressure fluctuations at the injection point

● Used together with pulse dampers to reduce water-hammer damage to the system

● Protects piping, elbows and fittings, reduces the impact of pressure fluctuations

● Delivers its full effect only when used with other line components such as pulse dampers
