Premium Fire Hydrant Isolation Valve (Resilient Seated Gate Valve)

Ensure unparalleled control and reliability for your fire protection and municipal water systems with our state-of-the-art Fire Hydrant Isolation Valve.

Designed for critical underground applications, this resilient seated gate valve provides robust, bubble-tight shutoff, crucial for isolating fire hydrants for maintenance, repair, or replacement without disrupting the wider water network. Built to exceed industry standards, it guarantees long-term performance and peace of mind.

Key Features & Benefits:

• High-Strength Ductile Iron Body: Constructed from premium ductile iron (ASTM A536), ensuring exceptional durability, resistance to stress, and a long service life in demanding underground environments.
• Fusion Bonded Epoxy Coating: Internally and externally coated with a certified fusion bonded epoxy (FBE) to AWWA C550 standards, providing superior corrosion protection against soil conditions, chemicals, and water, significantly extending the valve's lifespan.
• Resilient Wedge Gate: Features an EPDM-encapsulated ductile iron wedge that provides 100% bubble-tight shutoff, minimizing leakage and water loss while preventing debris accumulation.
• Non-Rising Stem (NRS) Design: Ideal for underground installation, the NRS design offers a compact profile and eliminates the need for a large stuffing box, enhancing robustness and reducing maintenance.
• Full Port Design: Maximizes water flow and minimizes pressure drop, ensuring optimal water delivery to the fire hydrant during critical operations.
• Corrosion-Resistant Stem: Equipped with a high-grade stainless steel stem (or bronze equivalent) for superior corrosion resistance and smooth, reliable operation over time.
• Triple O-Ring Stem Sealing: Provides multiple layers of defense against leakage, ensuring a watertight seal and preventing infiltration of contaminants.
• Versatile End Connections: Available with flanged, mechanical joint, or push-on end connections for flexible and easy integration into various piping systems.
• Low Operating Torque: Engineered for smooth, easy operation, requiring minimal force to fully open or close the valve.
• Maintenance-Free Design: Robust construction and advanced sealing technology minimize the need for routine maintenance, reducing operational costs.
