Ball Check Valves
All sizes 12” and under in stock and available for next day shipment
HDL® Ball Check Valves offer great operational reliability because of their construction and working principle.
The principle of these valves is a freely moving ball mounted in a valve housing in such a way that return flow is effectively prevented.
The metal ball is covered with an oil, sewage and sea water resistant rubber which provides a perfect and silent seal.
Valve constructed from ductile iron.
The special advantages of the HDL® Ball Check Valves are:
- Reliable operation without the danger of clogging
- Efficient operation even with small pressure differences
- No wear under normal conditions
- Maintenance-free and long life
These advantages make HDL® Ball Check Valves extremely suitable for use in systems where there is danger of clogging, such as sewage and storm water systems.
HDL ball check valves are available in sizes 2” to 24” and sizes 12” and under are available for next day shipment. Traditionally HDL ball check valves were the non-return valve of choicefor sewage systems, but more customers are finding these simple valves to be the most reliable non return valve for industrial, mining, and many other industries. And of course HDL continues to be a staple in the municipal industry, especially as a non-return valve for sewage lift stations.
