Versatile Design and Reliable Performance

The Non Return Valve Reflux Type is carefully engineered to prevent reverse flow across a wide range of industrial applications. Its swing-type structure and automatic operation ensure fluid only moves in the intended direction. With compatibility for various pipeline sizes and pressure conditions, it delivers dependable service for water, chemical liquids, oil, gas, and steam systems. Full-bore body construction guarantees minimal head loss and energy efficiency.

Simplified Installation and Maintenance

This valve supports both horizontal and vertical installations and features standard flanged ends that comply with Indian and British codes. The bolted cover enables straightforward inspection and maintenance, minimizing downtime. Manual operation with automatic flow control ensures ease of use without external actuators. Its robust construction ensures longevity and adaptability for multiple industries.

Built for Durability and Compatibility

Constructed with high-quality Cast Iron, Ductile Iron, or Cast Steel, and offering seat options in EPDM, Nitrile, or metal, the reflux-type valve is designed for harsh operating conditions. Gasket materials in rubber or PTFE further enhance resistance to chemicals and wear. Hydraulically tested to IS/BS standards, the valve ensures safety and performance integrity for all supported media and applications.

FAQs of Non Return Valve Reflux Type:

Q: How is the Non Return Valve Reflux Type installed in a pipeline?

A: The Non Return Valve Reflux Type can be installed in either horizontal or vertical pipelines. It comes with standard flanged ends as per IS codes, allowing easy connection to most pipeline systems. Proper alignment and securing of the flanges with bolts are essential to ensure leak-free operation and optimal performance.

Q: What types of media are suitable for this check valve?

A: This valve is engineered to handle a wide range of fluids, including clear water, sewage, chemical liquids, oil, gas, and steam. Its seat and gasket material options, such as EPDM, Nitrile, rubber, and PTFE, make it adaptable for various industrial applications.

Q: When should I use a reflux type non-return valve in my system?

A: Reflux type non-return valves are essential when preventing backflow is critical in fluid handling systems. They are ideal for applications in water supply, industrial pipelines, sewage systems, and chemical processing plants, especially where reverse flow can cause system contamination, damage, or inefficiency.

Q: Where can this valve be applied within industrial facilities?

A: This valve is suitable for installation in water and wastewater treatment plants, industrial process pipelines, pumping stations, and chemical distribution systems. Its robust design makes it applicable wherever reliable backflow prevention is required.

Q: What is the process for maintaining the valve?

A: Maintenance is straightforward due to the bolted cover design. Regular inspection involves unbolting the cover to check the integrity of the disc, seat, and gaskets. Cleaning and replacement of worn components can be performed easily, minimizing downtime and ensuring continued performance.

Q: How does the valve offer automatic flow control without an actuator?

A: The valve utilizes a swing-type single flap disc that automatically opens when fluid flows in the correct direction and closes when flow reverses. This mechanical action requires no external actuators or manual intervention after installation, providing reliable and automatic operation.

Q: What benefits does the full bore design provide?

A: The full bore design ensures minimal head loss and maintains high flow efficiency. It reduces turbulence and energy consumption within the pipeline, making it an energy-efficient solution for systems handling large volumes of fluid.
