2" Reduced Pressure Backflow Valve with Supervised Switch

The Zurn Wilkins 2" Reduced Pressure Backflow Valve with Supervised Switch isolates cross-contamination hazards and protects potable water supplies within commercial and residential fire protection systems. Installed inline to prevent backflow and back-siphonage, this assembly utilizes an integrated differential relief valve and an electronic supervised switch to continuously monitor operational status, instantly signaling valve faults or irregularities for proactive maintenance.

This assembly satisfies stringent life safety parameters mandated by industry regulations. It complies with NFPA requirements for backflow prevention in fire protection installations while carrying key UL and FM certifications necessary for commercial trade acceptance and facility code compliance.

Key Features & Construction

• Corrosion-Resistant Metal: Built from heavy-duty, corrosion-resistant materials engineered to withstand harsh mechanical rooms and long-term environmental exposure.
• Integrated Supervised Switch: Continuously monitors valve position and sends real-time status updates to your alarm panel to prevent undetected system compromises.
• 2-Inch Sized Footprint: Engineered with a 2-inch connection size to handle optimal flow performance required by fire protection applications.
• Reduced Pressure Principle: Features an internal relief valve between two independently operated spring-loaded check valves to reliably block contamination threats.

Technical Specifications & Compliance Table

Always verify local Authority Having Jurisdiction (AHJ) mandates, flow rates, and backflow assembly placement rules prior to starting your installation. Consult the manufacturer technical specifications for complete wiring diagrams, clearance dimensions, and testing procedures.
