Frequently Asked Questions – Wafer Type Non Return Valve (NRV)
What is a Wafer Type Non Return Valve (NRV)?
A Wafer Type Non Return Valve (NRV) is a compact valve designed to allow flow in one direction only. Its wafer-style design fits between flanges, saving space and simplifying installation in industrial pipelines.
What materials are Wafer Type NRVs made from?
Wafer NRVs are available in Cast Iron (CI), Mild Steel (MS), Stainless Steel (SS304/SS316), and Carbon Steel (WCB/CF8/CF8M). Material choice depends on fluid type, pressure, and temperature requirements.
What are the standard sizes and pressure ratings?
Wafer NRVs are typically available from 50 mm to 600 mm (2”–24”) with pressure classes ranging from PN10 to PN40 / ANSI 150–300. Custom sizes for bulk orders can also be supplied.
Which industries use Wafer Type NRVs?
These valves are widely used in water treatment, HVAC, chemical, petrochemical, power plants, and oil & gas pipelines where backflow prevention is critical for safety and efficiency.
How does a Wafer NRV prevent backflow?
The valve features a spring-loaded or gravity-assisted disc that closes automatically when flow reverses, ensuring zero backflow and protecting pumps, compressors, and other equipment.
Can Wafer NRVs be used in high-temperature applications?
Yes. Depending on the material, Wafer NRVs can handle fluids up to 200°C for stainless steel and 120°C for cast iron. Always check the valve’s material specification for precise limits.
How do you maintain a Wafer Type NRV?
Maintenance is minimal. Periodic inspection of the disc, hinge, and seat ensures reliable operation. Cleaning deposits and checking for corrosion will extend valve life, especially in bulk industrial pipelines.
Are Wafer NRVs available for bulk orders and OEM supply?
Yes. Manufacturers like Kelor Valves offer bulk supply, OEM branding, and custom packaging for international shipping. Pricing scales with quantity and material selection.
What is the price range for Wafer Type NRVs?
Prices depend on size, material, and quantity. Typical range: ₹130 to ₹5,500 per piece. Bulk and export orders are eligible for discounted pricing.
How can I request a quote for Wafer Type NRVs?
You can request a quote directly from suppliers like Kelor Valves via phone, email, or website inquiry. Provide size, material, quantity, and pressure class for an accurate bulk quotation.
