The 4" Wafer Swing Check Valve with 1/2" Ball Connection is a critical component designed for fire protection and plumbing professionals needing reliable backflow prevention within compact piping systems. Its slim wafer-style design and integrated test port enhance operational safety and simplify maintenance in fire sprinkler and potable water applications.

• Material Construction: Built from high-grade ductile iron that offers excellent strength and corrosion resistance, paired with 300-series stainless steel internal parts designed to endure frequent pressure changes and cycling without degradation.
• Wafer-Style Design: Compact and lightweight, this valve fits securely between ANSI B16.1 standard flanges or compatible mechanical joints, making it ideal for installations in tight or constrained spaces typical of fire protection systems.
• 1/2" Ball Connection: Includes a built-in ball valve connection that facilitates easy attachment of pressure gauges or testing devices, allowing NFPA-compliant checks and diagnostics without interrupting system flow.
• Seating and Seal Technology: Features precision-machined elastomer seals that guarantee a tight shutoff, effectively preventing reverse water flow and protecting system integrity during pressure surges or pump shutdowns.
• Regulatory Certifications: UL 786 Listed and FM Approved, compliant with NFPA 13 and NFPA 25, ensuring it meets rigorous safety and performance standards required in fire sprinkler and inspection systems.
• Pressure Rating: Rated for reliable operation up to 175 PSI (12.1 bar), making it well-suited for medium to high-pressure fire sprinkler risers and branch lines.
• Installation Flexibility: Designed for both horizontal and vertical pipeline use, with clear flow direction markings that minimize installation errors and streamline setup.

This valve addresses the essential need for dependable backflow prevention in commercial and industrial fire protection networks. By blocking reverse flow, it reduces contamination risks and prevents damage from pressure fluctuations or pump failures. The integrated 1/2" ball connection streamlines testing and maintenance, saving time and supporting compliance with inspection standards. Its durable materials combined with a space-saving design help lower installation and long-term replacement costs, ensuring fire protection systems remain ready and reliable. Ideal for professionals focused on enhancing the safety, efficiency, and longevity of sprinkler system operations.
