10" 4000SSLG Backflow Preventer Valve

Protect municipal water supplies, industrial facilities, and fire suppression infrastructure from reverse flow contamination with the 10" 4000SSLG Backflow Preventer Valve. This specialized assembly secures water system integrity in high-demand commercial plumbing, irrigation networks, and fire protection setups. It operates directly in compliance with NFPA 13 and NFPA 25 standards, satisfying mandatory code requirements for routine testing, inspection, and the preservation of potable water safety.

Stainless steel springs and precision-machined check mechanisms maintain positive sealing under working pressures up to 175 PSI while minimizing pressure loss. Durable elastomer seals provide reliable shutoff performance, and a bolted cover design grants straightforward access for internal inspections and seal replacements during scheduled maintenance.

• Precision Internals: Utilizes stainless steel springs and machined check mechanisms to positively prevent reverse flow.
• Flexible Installation: Mounts securely in horizontal or vertical upflow piping configurations.
• Optimized Flow Performance: Minimizes pressure drop across the assembly to enhance overall system efficiency.
• Accessible Maintenance Design: Features a bolted cover that simplifies internal inspections and seal replacements.

Contractors must verify local Authority Having Jurisdiction (AHJ) mandates and review site-specific engineering requirements prior to installation. Note that this specialized hardware is non-cancellable and non-refundable.
