1/4 Inch UCDBINJ Injection Check Valve Function: Accessories that prevent the reverse flow of fluid in pipelines or injection systems, prevent backflow, ensure that the fluid flows only in one direction, and avoid reverse flow or system pressure imbalance. Maintain a stable pressure in the system to prevent the pump from being damaged due to backflow Application Scenarios：Fits for most Sten-ner pump such: 45 85 100 170 Series,S420 S128 S10P VX SV, S series peristaltic pump parts,classic series, single head；Water supply system, irrigation system etc Easily Solve The Following Problems: Due to the aging of the equipment causing reverse leakage, equipment blockage, and the need for cleaning or maintenance, rapid shutdown may cause pressure shock problems Easy to install: The arrow on the valve body must be consistent with the direction of the fluid. It is usually installed between the pump outlet and the injection point, close to the injection end, to reduce backflow. Regularly inspect the equipment. If a reduction in flow or leakage is detected, the check valve needs to be cleaned or replaced Excellent Material: Made of PC+TPE+PP materials, it features high strength and toughness, excellent impact resistance, is not prone to breakage, and has strong wear resistance. The check valve kit can meet your daily equipment maintenance and replacement needs, protect equipment safety, and maintain stable system operation., Weight: 0.1 pounds, Manufacturer: Earthtec
