What is the purpose of a non-return valve?

Preventing Contamination

In systems where clean or sterile conditions are crucial, non-return valves prevent contaminated fluids from re-entering the system.

Maintaining Pressure

Non-return valves help maintain pressure levels by preventing fluids from flowing backward and causing pressure drops.

Avoiding Pump Damage

In pump systems, backflow can damage pumps and decrease their efficiency. Non-return valves protect pumps by preventing reverse flow.

Safety

Non-return valves can play a safety role by preventing potentially hazardous substances from accidentally flowing backward.

Regulating Flow

In some cases, non-return valves are used to control the flow rate by allowing fluids to flow only in the desired direction.
