Ball Check Valve is the main stream product type for the waste-water industry.
Internal and ball structure enables, non-stop functioning, self-cleaning and with full bore.
Operation is based on a free ball inside the body which is pushed by the pumped flow to the side cavity, allowing the liquid pass through.
When the pump stoped and the ball is no longer pushed aside, it drops back in the inlet port and prevents flow returns.
Ball check valves are available with flanges and internal threads.
