Top quality, epoxy coated ball check valves with full flow passage. Suitable for sewage and wastewater applications.

How it works
As fluid starts to flow, the ball moves out of the stream to allow full passage of solid material. When the flow stops, the ball returns under gravity and seals the inlet, preventing back flow. The ball rotates randomly during operation to prevent build up of deposits on the ball surface.
