Product Description

 

Ductile Iron Threaded Ball Check Valve, Scerwed Ball Check Valve, Ductile Iron Threaded Ball Check Valve/ductile iron Scerwed Ball Check Valve
 

The ball check valve is mainly used in wastewater applications, power plants and process industry. The ball check valve is suitable for use in polluted media as the ball shaped valve prevents the buildup of dirt. Typically a wastewater lift station will have a ball check valve to prevent reverse flow. This is why sometimes these valves are called non-return valves. A ball check valves operate best with 3-5 feet per second velocity and 20 feet of head pressure.
