LBF series liquid back pressure valve, adopts diaphragm type structure, used for diaphragm pressure transmission, for pump outlets,stable pressure,stable flow, prevents liquid backflow,it can also be installed on a branch line as a relief valve. Used together with a damper, reduces liquid pulsation.
● 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
