CPVC Swing Check Valve — 1 in. Socket x Socket — Spears FlameGuard™ — S1520-10CO
The Spears FlameGuard™ 1 in. CPVC swing check valve prevents reverse water flow in CPVC wet fire sprinkler systems. Constructed from fire-protection-grade CPVC, it offers excellent corrosion resistance and long-term strength in high-moisture environments. The valve uses a swinging disc mechanism that automatically closes when flow stops, helping maintain system pressure and prevent backflow. Both socket ends connect to CPVC pipe using ASTM F493-approved solvent cement for a watertight joint.
Install following Spears FlameGuard™ recommendations for orientation, pipe preparation, and cementing. Ensure that the valve is installed in the proper flow direction as marked on the body. The durable CPVC construction provides long-lasting, corrosion-resistant performance while maintaining code compliance. This swing check valve ensures reliable backflow prevention in wet fire sprinkler systems.
