1/2" PVDF Venturi Injector When pressurized water enters the injector inlet, it is constricted toward the injection chamber and changes into a high-velocity jet stream. The increase in velocity through the injection chamber results in a decrease in absolute pressure, creating a vacuum, thereby enabling an additive material to be drawn through the suction port and entrained into the water stream. As the jet stream is diffused toward the injector outlet, its velocity is reduced and it is reconverted into lower pressure energy. Heavy Duty KYNAR ozone resistant material Helps add flow to low flow situations High quality design Additional Details ------------------------------ Package quantity: 1 Part number: A2Z-0.5 MPN: A2Z-0.5
