2.5″ NRV Valve CI (Non Return Valve)
The 2.5 inch NRV Valve CI (Non Return Valve) is a high-performance flow control solution designed to prevent reverse flow in fire fighting, industrial, and commercial piping systems. Manufactured from high-grade cast iron, this valve ensures long service life, reliable operation, and excellent resistance to corrosion and pressure stress. At Fire Safe Pakistan, we supply quality-tested NRV valves suitable for demanding environments across Pakistan.
Durable Cast Iron Construction
This non return valve is built using premium quality cast iron (CI), making it highly durable and suitable for continuous operation. The robust body structure resists corrosion, pressure fluctuations, and mechanical wear, ensuring dependable performance in both indoor and outdoor installations.
The polished or satin body finish adds an extra layer of protection against environmental damage while maintaining a professional industrial appearance.
Reliable Swing-Type Non Return Mechanism
The swing-type design allows smooth, unidirectional flow and automatically shuts off when reverse flow occurs. This feature is critical in fire protection systems, water supply lines, and industrial fluid control, where backflow prevention is essential for safety and system efficiency.
The valve is engineered to provide minimal pressure drop, ensuring optimal flow efficiency without compromising system performance.
High Pressure and Temperature Performance
Designed for demanding applications, this 2.5″ CI NRV valve supports working pressure up to 300 PSI, making it suitable for high-pressure pipelines. It operates efficiently within a temperature range of -20°C to 200°C, allowing use in extreme environmental and industrial conditions commonly found in Pakistan.
Advanced Sealing and Disc Technology
The valve features a Teflon-coated disc, which enhances sealing performance and significantly increases service life. This coating reduces friction, improves closing response, and ensures consistent operation over time.
For sealing, EPDM or NBR materials are used, offering excellent resistance to chemicals, temperature variations, and pressure, making the valve ideal for fire water systems and industrial fluids.
Secure Flanged End Connections
Equipped with flanged end connections, the valve allows safe, leak-free, and flexible installation. Flanged joints ensure strong alignment, easy maintenance, and compatibility with standard piping systems used in fire fighting and industrial installations across Pakistan.
Tested, Certified, and Quality Assured
Each NRV valve undergoes hydrostatic and pneumatic testing to ensure leak-proof performance and operational reliability. UL/FM certifications are available depending on stock and project requirements, making this valve suitable for certified fire protection systems.
Fire Safe Pakistan ensures that all certifications and compliance documents are confirmed at the time of order.
