850 Series Double Check Valve Assemblies

Watts 850 Series double check valve assemblies are used in plumbing & water supply systems to ensure water safety and prevent backflow. These assemblies protect the potable water supply from potential contaminants that could enter the system due to back-siphonage or backpressure. They have a dual-check valve configuration for double protection against backflow. These valve assemblies feature a modular design for quick inspections and repairs. They have bronze construction for structural rigidity and leakproof operations. These valve assemblies have silicone discs for improved sealing during operations and offer rough bronze finish to resist corrosion on exposed surfaces.
