10" Double Check Valve Non Rising Stem Flange

The 10" Double Check Valve Non Rising Stem Flange by Zurn Wilkins functions as a specialized backflow prevention assembly engineered for commercial and industrial fire protection and plumbing systems. Installed within mainline water supply networks, this valve prevents the reverse flow of non-potable substances into potable water supplies. Operating via two independent check valves, it isolates hazards to maintain system integrity and safeguard water quality during backpressure or backsiphonage events.

This assembly satisfies mandatory safety and regulatory requirements established under NFPA codes, alongside UL and FM standards for commercial fire safety equipment. The integrated non-rising stem design ensures the valve stem remains compact within the housing during operation, making it the ideal choice for tight mechanical rooms or installations with restricted vertical clearance.

• Size: 10-inch nominal diameter fits medium to large-scale infrastructure piping.
• Valve Mechanism: Dual independent check valves collaboratively stop backflow and protect water quality.
• Stem Configuration: Non-rising stem design allows for operation in restricted spaces without extra clearance requirements.
• Connection Type: Secure flange mounting simplifies system integration, inspection, and maintenance.
• Material Construction: Built with corrosion-resistant, rust-mitigating materials to withstand harsh mechanical environments.

Trade contractors and facility engineers must verify local Authority Having Jurisdiction (AHJ) mandates and consult manufacturer technical cut sheets prior to final installation to ensure complete project compliance.
