What is a Check Valve?

A Check Valve, also known as a Non-Return Valve (NRV), One-Way Valve or Backflow Prevention Valve, is designed to allow fluid (liquid or gas) to flow in one direction only, preventing reverse flow in pipelines. It operates automatically, requiring no manual intervention or external control, making it a critical component in various industries. The valve typically consists of a disc, ball or clapper that opens when the forward flow pressure exceeds the cracking pressure and closes when the pressure reverses or drops.

Where are Check Valves Used?

Check valves are widely used across multiple industries, ensuring smooth and reliable flow control in critical applications.

  • Oil & Gas Industry- Prevents reverse flow in pipelines, ensuring continuous operation in crude oil, gas processing, and refining plants. Used in offshore drilling, refineries, and natural gas distribution to maintain flow direction.
  • Water Treatment & Plumbing- Stops contaminated water from flowing back into clean water supply lines, ensuring hygiene and safety. Used in sewage treatment plants, desalination plants, and municipal water systems.
  • Chemical & Petrochemical Plants- Prevents backflow of hazardous chemicals, avoiding contamination and equipment damage. Used in aggressive chemical processing environments where corrosion-resistant materials like Hastelloy, Duplex Stainless Steel and Monel are preferred.
  • Power Generation & Energy Plants- Ensures proper steam and water flow in boilers, condensers, and cooling systems in thermal, nuclear, and hydroelectric power plants. Maintains pressure and prevents backflow in high-pressure turbine and generator systems.
  • Food & Beverage Industry- Maintains hygiene by preventing backflow in processing pipelines, ensuring compliance with food safety regulations. Commonly used in dairy, breweries and beverage processing plants.
  • HVAC, Fire Protection & Building Services- Helps maintain pressure in heating, ventilation, and air conditioning (HVAC) systems. Used in fire protection systems to prevent water backflow, ensuring fire sprinklers function correctly.

Type of Check Valve we offer



Dual Plate Check Valve

Dual Plate check valve also known as a double disc check valve comes with a compact design, a heavy-duty spring that reacts swiftly when there are any changes in flow, and quick closing. Dual Plate Check Valve is super easy to install and maintain whenever maintenance is required.


Swing Check Valve

Swing check Valve also known as tilting disk check Valve, has a disc that swings on a hinge which allows forward flow and prevents reverse flow. The disc acts as a stopper when there is enough pressure to withstand the cracking pressure.


Lift Check Valve

Lift Check Valve operates with a lift mechanism that uses a piston or a ball to control liquid flow, lift check valves are most suitable for water applications and applications with high-pressure conditions. To open and close these check valves use a disc that goes up and down, and closes either by spring or simply by gravity.


Wafer Check Valve

Also known as a butterfly check valve, these check valves are designed to fit between two flanges. It has a wafer or disk supported by a spring and attached to a hinge. These valves are lightweight, cost-effective, easy to install, and suitable for applications where space is very limited. It operates unidirectional while preventing backflow, when the flow stops or reverses, due to gravity and backflow pressure the disc then returns to a close position.
