Non-return valve allows a medium to flow in only one direction and is used to ensure that the medium flows through a pipe in the correct direction, even when pressure conditions would normally cause reverse flow. The flow via the non-return valve results in a relatively substantial pressure loss, which must be considered while building the system.

In simple words Non return valves or NRVs are small, meek, and reasonable units whose main function is to allow fluid to only run in one direction.

At Perfect Engineers, we put Non Return Valve through many testing to ensure that it holds the best attributes. We are the top exporter and manufacturer of Non Return Valve in Mumbai, India.

Types of Non Return Valves

Pneumatic Non Return Valve
Perfect Engineers is one of the leading Manufacturers, Supplier of Brass Quick Release coupling. We provide superior quality products made according to Indian and international standards

Hydraulic Non Return Valve
Hydraulic non-return valves, also known as check valves, are utilized in hydraulic systems to allow fluid flow in one direction while preventing reverse flow, maintaining system pressure and preventing damage to components.

Check Valves
Check valves are a general category of non-return valves that are used in various fluid systems, including pneumatic, hydraulic, and plumbing systems. They allow flow in one direction while automatically blocking flow in the opposite direction, ensuring uni-directional flow and preventing backflow.

Features of Non Return Valve

  • Protection against Contamination: NRVs guarantee that fluids flow solely in the appropriate direction, preventing contamination and maintaining purity. 
  • Energy Saving: By reducing fluid backflow, NRVs help to conserve energy and lower operational costs.
  • Extended Equipment Life: Preventing backflow decreases stress on equipment, resulting in longer service life. 
  • Improved System Efficiency: NRVs help to maintain consistent flow rates, which improves overall system efficiency. 
  • Enhanced Safety: In sectors that work with hazardous products, NRVs add an added degree of protection by reducing leaks and spills.

Application Of Non Return Valve

  • Piping Systems: Non-return valves are commonly installed in piping systems to ensure that fluids flow in one direction only, preventing backflow and maintaining system integrity. They are used in both industrial and residential piping systems to prevent contamination and damage to equipment.
  • Hydraulics: In hydraulic systems, non-return valves are essential components for controlling the flow of hydraulic fluids. They allow fluid to flow in one direction while preventing reverse flow, ensuring smooth operation and preventing damage to hydraulic components.
  • Pneumatics: Non-return valves play a crucial role in pneumatic systems by allowing air or gasses to flow in one direction only. They are used to maintain pressure and control the direction of airflow in pneumatic circuits, ensuring efficient operation of pneumatic machinery and equipment.
