3" Reduced Pressure Assembly Z Grooved Butterfly Valve

The 3" Reduced Pressure Assembly (RPA) with a "Z" Grooved Butterfly Valve is designed for professionals managing fire protection and domestic water systems who require dependable backflow prevention combined with efficient flow control. Its durable construction and compliance with key industry standards make it a reliable choice for maintaining water safety and system integrity.

• Construction Material: Heavy-duty, epoxy-coated ductile iron ASTM A536 body resists corrosion and mechanical stress for long-term durability.
• Internal Components: Springs and fasteners built from 300-series stainless steel provide corrosion resistance in demanding environments.
• Valve Design: Precision-machined stainless steel butterfly disc and seat for accurate flow regulation and positive shutoff.
• Backflow Prevention: Dual independently-acting check valves with resilient EPDM seats ensure effective reduced pressure backflow control.
• Connection Type: "Z" grooved ends compliant with AWWA C606 allow fast, welding-free installation using standard grooved pipe couplings.
• Pressure & Temperature Ratings: Supports operating pressures up to 175 PSI and temperatures from 33°F to 140°F, suitable for residential and light commercial systems.
• Regulatory Compliance: UL Listed (UL 312), FM Approved, ASSE 1013 certified, and compliant with NFPA 13 and NFPA 25 for fire sprinkler system standards.
• Installation Versatility: Designed for fire sprinkler risers, underground fire service lines, and water feed mains, capable of withstanding mechanical room conditions and subterranean use.

This assembly addresses the critical challenge of preventing contamination in potable water by reliably stopping backflow from firefighting chemicals and pollutants. Its grooved butterfly valve design significantly reduces installation time and labor costs compared to traditional valves, making it especially valuable for contractors and system maintainers seeking efficiency and compliance. By maintaining flow performance with minimal pressure loss, it helps ensure optimal fire protection system functionality while simplifying maintenance with its positive shutoff feature. This product is ideal for scenarios demanding robust backflow prevention with straightforward installation in compact or constrained spaces.
