In the industrial world, fluid control is critical — and when it comes to preventing reverse flow, Non Return Valves (NRVs) are essential. Among the many standards that guide valve performance in India, IS 5312-2 stands out as the benchmark for quality, safety, and durability.
India is home to several reputable Non Return Valve manufacturers, producing IS 5312-2-compliant valves that meet the demands of waterworks, industrial processing, irrigation, and more. This article explores why Non Return Valves made in India under this standard are trusted across industries and how they contribute to efficient and safe flow control.
What Is a Non Return Valve?
A Non Return Valve, also known as a check valve, allows fluid to flow in only one direction and automatically closes to prevent backflow. This feature protects pumps, compressors, and pipeline systems from damage and contamination.
These valves are widely used in:
- Water supply and distribution systems
- Wastewater treatment plants
- Industrial processing plants
- Power generation systems
- Fire protection lines
Understanding IS 5312-2
IS 5312-2 is the Indian Standard for swing-type metallic Non Return Valves, specifically designed for use in waterworks and general industrial applications. Valves manufactured under this standard meet precise specifications for materials, design, dimensions, and testing methods.
Key highlights of IS 5312-2 include:
- Suitable for PN 1.0 and PN 1.6 pressure classes
- Flanged construction for secure installation
- Available in standard sizes (typically from 1” to 28”)
- Hydrostatic and leakage testing for quality assurance
- Durable materials like cast iron, ductile iron, and stainless steel
Made in India – Quality You Can Trust
India has established itself as a global hub for industrial valve manufacturing, and IS 5312-2 Non Return Valves are no exception. Manufacturers in Ahmedabad, Gujarat, and other industrial cities produce valves that adhere to international quality benchmarks.
Key features of Indian-made IS 5312-2 NRVs include:
- Precision engineering to ensure smooth operation and leak-free performance
- Cost-effective manufacturing without compromising quality
- Availability in bulk for infrastructure, water boards, and export
- Compliance with Indian and global standards
Swing-type NRVs are best suited for water-based systems with lower to moderate flow velocities — exactly what IS 5312-2 supports.
Applications in Industrial Systems
Non Return Valves as per IS 5312-2 are ideal for:
- Municipal water supply lines – Preventing contaminated water from re-entering the clean supply
- Pump stations – Protecting pumps from back-pressure
- Irrigation projects – Ensuring controlled flow in open-channel and pipeline systems
- Fire protection systems – Maintaining constant readiness without backflow risk
Choosing the Right Manufacturer in India
If you’re sourcing Non Return Valves that meet IS 5312-2, it’s important to choose a manufacturer with:
- A certified valve factory in Ahmedabad or other industrial regions
