What are check valves used for?
2025-09-12
1. Protecting Equipment:
Pumps: Installed on the outlet side of pumps, check valves prevent backflow when the pump stops, protecting it from damage and ensuring proper operation upon restart.
Heat Exchangers: Placed in circuits, check valves direct the flow through the exchanger in the intended direction, maximizing heat transfer efficiency and preventing cold and hot fluids from mixing.
2. Preventing Backflow Contamination:
Plumbing Systems: Check valves in water supply lines prevent contaminated water from entering clean water sources, ensuring safe drinking water and preventing cross-contamination.
Sewage Systems: Installed in drainage systems, check valves stop sewage from backing up into buildings or flowing in the wrong direction, preventing health hazards and property damage.
3. Maintaining Pressure:
Air Conditioning Systems: Check valves in condensate drainage lines prevent the backflow of condensate, ensuring proper drainage and maintaining efficient operation of the AC unit.
Hydraulic Systems: Used in pressurized lines, check valves maintain pressure by preventing fluid from flowing back to the reservoir, ensuring proper functioning of hydraulic machinery.
