Core Functions:Backflow Prevention: During the suction stroke of the metering pump, the check valve closes automatically to block medium in the outlet pipeline from flowing back into the pump chamber, ensuring accurate and stable dosing each time.
Metering Accuracy Protection: Eliminates metering errors caused by backflow and maintains the dosing accuracy of the chemical feeding system.
Corrosion Resistance: Made of 316L stainless steel, it can withstand corrosive media such as acids, alkalis and salts, and is suitable for harsh working conditions in chemical, environmental protection and other industries.
Application Scenarios:
Specially used in the outlet pipelines of metering pumps (dosing pumps), it is widely matched with metering pump dosing systems in water treatment, chemical, environmental protection, pharmaceutical and other industries, serving as a key wearing part for regular maintenance of metering pumps.
