Introducing the 505SB Silicon Bronze Check Valve, a dependable backflow prevention solution for plumbing and irrigation systems. Crafted from durable silicon bronze, this valve resists corrosion and maintains strong performance under pressure. Its lead-free construction makes it safe for potable water applications, while a compact, rugged design suits both residential and commercial installations, delivering reliable protection against reverse flow.

Benefits Paragraph: This backflow prevention device stops reverse flow, preserving water quality and system integrity. With lead-free material and a robust build, it is ideal for drinking-water lines, irrigation networks, and other critical applications requiring safe, code-compliant backflow control.

• Lead-Free Silicon Bronze Body: Durable, corrosion-resistant housing that ensures safe potable water delivery and dependable backflow prevention.
• 1-1/2 Inch Female Threaded (FPT) Connections: Easy installation in standard piping and irrigation runs with compatible male fittings.
• High-Pressure Rating (400 PSI): Handles demanding water mains and commercial-grade systems without compromising performance.
• Temperature Rating up to 210°F: Suitable for hot-water lines and varied climates while maintaining seal integrity.
• Included Sealing Hardware: Buna-N O-ring, stainless steel spring, washer, and locknut provide a secure seal and long service life.

Why This Valve Stands Out: The 505SB combines safety, compliance, and durability in one compact package. It protects potable water supplies, supports code-compliant installations (California), and offers straightforward installation for professionals and DIY enthusiasts alike. When backflow prevention matters, this valve delivers consistent performance and peace of mind.
