Key Considerations for Vulcanised Nitrile Rubber (NBR) Lined Duplex Butterfly Valves

When selecting or buying Vulcanised Nitrile Rubber (NBR) lined duplex butterfly valves, there are several key considerations to keep in mind:

1. Valve Size and Pressure Rating: Ensure that the valve size and pressure rating are compatible with the intended application to avoid leaks or other performance issues.

2. Temperature and Chemical Compatibility: Check the temperature and chemical compatibility of the NBR lining with the fluids or gases that will pass through the valve to prevent chemical attack or degradation.

3. Quality and Certification: Verify that the valves meet industry standards and certifications to ensure reliability and performance. Look for ISO, API, or other relevant certifications.

4. Valve Body Material: Consider the material of the valve body to ensure compatibility with the operating environment and to prevent corrosion or other damage.

5. Operational Requirements: Evaluate the operating conditions such as flow rate, frequency of operation, and pressure variations to select a valve that can meet the specific requirements.

6. Sealing Performance: Check the sealing performance of the valve to prevent leakage and ensure tight shut-off when the valve is closed.

7. Manufacturer Reputation: Choose valves from reputable manufacturers with a track record of quality products and good customer service to ensure long-term reliability and support.

8. Cost and Value: Consider the overall cost of ownership, including initial purchase price, maintenance costs, and lifespan of the valve to determine the value it provides.

By considering these key factors, you can select Vulcanised Nitrile Rubber (NBR) lined duplex butterfly valves that best fit your industrial application requirements.
