A non-return valve (also known as a check valve) is a mechanical device used to allow fluid (liquid or gas) to flow in one direction only and prevent backflow in the opposite direction. It operates automatically, without the need for manual intervention, to ensure that fluids do not reverse their flow and cause damage or malfunction to a system.


We CAPRO VALVES make available to our clients best quality of NON RETURN VALVES with Key features as follows :


Flow Direction : The valve opens to allow fluid to flow in the intended direction and closes to prevent backflow.

Automatic Operation : Our Non-return valves do not require external power or control to function.

Applications : Common in systems such as water supply systems, oil pipelines, HVAC systems, and pumps, among others.


Our Non Return Valves find Applications as follows :


Pumps : To prevent backflow into the pump, which could cause damage.

Water Treatment Systems : To prevent contamination by keeping water flowing in one direction.

Heating Systems : To prevent backflow of hot water into the cold supply.

Oil & Gas Pipelines : To prevent reverse flow and ensure the efficiency of the system.


Common Advantages :


Prevents Damage : By avoiding reverse flow, it helps protect equipment from damage.

Reduces Contamination Risks : Keeps systems clean by ensuring that substances do not flow in the wrong direction.

Simple & Reliable : Most non-return valves are simple mechanical devices that do not need complicated control systems.
