1. Design and Construction

Resilient seated gate valves are designed with a rubber or elastomeric material lining, providing a flexible seal that enhances sealing capabilities. Traditional gate valves, meanwhile, often use a metal-on-metal sealing mechanism, which can lead to leaks over time. The use of a resilient seat in the AWWA resilient seated gate valve is specifically aimed at improving the overall functionality and longevity of the valve.

2. Performance in Different Conditions

Resilient seated gate valves generally perform better in harsh conditions, including varying temperature ranges and water quality. Their rubber lining allows for better adaptability to changes, reducing the risk of damage from corrosion or sediment build-up. Traditional gate valves may struggle in similar situations since their metal components can corrode and wear down more quickly.

3. Maintenance Requirements

When it comes to maintenance, resilient seated gate valves typically require less attention. The materials used in their construction can reduce wear and tear, leading to longer service intervals. On the other hand, traditional gate valves may require more frequent inspections and maintenance to ensure they function properly, as their metal components are more susceptible to deterioration.

4. Installation Considerations

Installation can also differ between the two types of valves. AWWA resilient seated gate valves often come with lighter materials, making them easier to handle and install. Traditional gate valves can be heavier and bulkier, which may complicate the installation process, especially in tight spaces.

5. Cost Implications

From a cost perspective, resilient seated gate valves may have a higher initial purchase price compared to traditional gate valves. However, their durability and lower maintenance costs can make them more cost-effective in the long run. Traditional gate valves might seem cheaper up front, but the potential for increased maintenance and shorter lifespans can add up over time.

Why Consider AWWA Resilient Seated Gate Valves?

The AWWA resilient seated gate valve is an excellent choice for both residential and industrial applications due to its various advantages. Here are a few reasons to consider them:

1. Enhanced Sealing

With a resilient seat, these valves provide superior sealing, preventing leaks and ensuring better control over the flow of water.

2. Longevity

Thanks to their robust design and materials, AWWA resilient seated gate valves are built to last, reducing the frequency of replacements.
