Back Pressure/Pressure Relief Valves  LMI's diaphragm back pressure/anti-syphon valves apply positive discharge pressure to a metering pump system and act to stabilize the output of higher output LMI Metering Pumps when pumping into low or no-pressure systems. Pressure relief valves are designed to protect chemical feed systems from overpressure damage caused by defective equipment or deadheading. Valves are available in 1/4”, 1/2”, and 1” sizes in PP, PVC, PVDF, and 316SS. Four Function Valve (4FV) This compact and economical valve performs four important functions for your LMI pump: 1.Diaphragm type anti-syphon protection 2. Back pressure 3. Priming aid/line drain 4. Pressure Relief Priming with the 4FV is simple and is achieved by _ turn of the pressure relief knob.
