AVK Unveils Next-Generation Resilient Seated Gate Valves for Water Infrastructure
Water infrastructure networks around the world are facing increasing pressure. Aging pipelines, rising demand, and stricter environmental regulations mean that utilities are investing heavily in modernising distribution systems. In response, AVK has introduced a next-generation resilient seated gate valve designed specifically for long-term reliability in water infrastructure.
The updated valve design focuses on durability, corrosion protection, and ease of maintenance — all critical factors for underground installations where accessibility is limited and service life expectations can exceed decades.
WHAT MAKES RESILIENT SEATED GATE VALVES IMPORTANT IN WATER NETWORKS
Resilient seated gate valves are widely used in potable water distribution systems because they offer tight shut-off, low headloss, and simple operation. Unlike traditional metal-seated gate valves, these designs use an elastomer-coated wedge that creates a bubble-tight seal against the valve body.
In municipal water systems, this type of valve is typically used for:
• Pipeline isolation
• Network segmentation
• Maintenance shutdowns
• Pressure management
The ability to completely stop flow without significant pressure loss when fully open makes resilient seated gate valves an essential component of water networks.
KEY IMPROVEMENTS IN AVK’S LATEST DESIGN
AVK’s latest resilient seated gate valve generation introduces several design improvements aimed at increasing operational reliability and service life.
Key developments include:
• Enhanced corrosion protection coatings for buried installations
• Improved elastomer wedge materials for long-term sealing performance
• Optimised stem sealing systems to reduce leakage risk
• Increased resistance to wear from frequent operation
• Compatibility with modern water infrastructure standards
These upgrades address common challenges faced by utilities, particularly corrosion and sealing degradation over long operational periods.
DESIGNED FOR LONG-TERM UNDERGROUND SERVICE
Valves used in water distribution systems are often buried underground for decades. This means materials and coatings must provide exceptional resistance to soil conditions, moisture, and potential contamination.
The new AVK design incorporates advanced epoxy coatings and corrosion-resistant materials that protect the valve body and internal components. This is essential for maintaining performance over extended lifecycles, especially in aggressive soil environments.
For operators, durability translates directly into lower maintenance costs and fewer unexpected failures.
COMPLIANCE WITH MODERN WATER INDUSTRY REQUIREMENTS
Water utilities increasingly require valves to meet strict regulatory and certification requirements. These may include compliance with potable water standards, pressure testing requirements, and operational durability benchmarks.
AVK’s next-generation resilient seated gate valves are designed to align with modern water industry specifications, ensuring they meet the expectations of:
• Municipal water utilities
• Infrastructure contractors
• Engineering consultants
• Network maintenance teams
In critical infrastructure systems, consistent quality and certification are just as important as mechanical performance.
SUPPORTING FUTURE WATER INFRASTRUCTURE PROJECTS
Water infrastructure upgrades are accelerating worldwide as governments invest in improving distribution networks and reducing leakage levels. Isolation valves play a key role in this process by allowing utilities to manage network sections without disrupting supply.
Resilient seated gate valves remain a preferred solution because they offer simple operation, long service life, and reliable sealing performance in buried installations.
With its updated design, AVK is positioning this valve technology to support the next generation of water infrastructure projects.
As water networks continue to expand and modernise, the importance of reliable isolation valves cannot be overstated. AVK’s next-generation resilient seated gate valve reflects the industry’s ongoing focus on durability, corrosion resistance, and operational reliability.
For engineers and water utilities, selecting high-quality valves ensures that infrastructure investments deliver long-term performance, reduced maintenance, and dependable water distribution for decades to come.
