The Resilient Seat Gate Valve is a high-performance industrial solution engineered for superior sealing and durability in water distribution and wastewater systems. Designed in strict accordance with AWWA C509 standards, this valve features a resilient-seated wedge that ensures a bubble-tight shut-off, minimizing leakage and reducing maintenance costs for large-scale infrastructure projects.
Constructed with high-grade ASTM A536 ductile iron and protected by a fusion-bonded epoxy coating both inside and outside, our gate valves offer exceptional resistance to corrosion and wear. With a versatile size range up to 40 inches and compliance with ASME B16.1 and B16.10, these valves provide seamless integration into global piping networks, ensuring operational reliability in the most demanding environments.

Frequently Asked Questions
A resilient seat, typically made of NBR, provides a bubble-tight seal that can accommodate small particles or imperfections in the seating area, whereas metal seats are more prone to leaking if any debris is present.
Yes, fusion bonded epoxy is highly recommended for underground applications as it provides an impermeable barrier against soil chemicals and moisture, preventing corrosion.
Our valves are manufactured according to AWWA C509, with flange dimensions following ASME B16.1, face-to-face dimensions per ASME B16.10, and testing based on API 598/EN12266.
We provide a wide range of sizes, reaching up to 40 inches (DN1000) and beyond for specific project requirements, as indicated in our technical dimensions table.
Yes, while the standard is a handwheel, the ASTM B16 stem can be adapted for electric or pneumatic actuators depending on your system's automation needs.
All valves are supplied with material test reports (MTRs) confirming the use of ASTM A536 ductile iron and other specified high-grade alloys.
