HDL ball check valves are ideally suited for all situations where liquid containing solid particles must be prevented from flowing back without the danger of clogging.
The firm Nodular cast Iron construction and deliberate design -- built on many years of experience and development -- delivers positive backflow prevention. Plus, HDL's current range of ball check valves is available in a comprehensive range of versions to suit almost any application.
In particular, Sunair Co. recommends HDL ball check valves for use in wastewater applications, because they feature a single moving part: a weighted, rubber-covered ball. This ball moves into pocket, so that it is fully outside the flow stream. This means these valves are less prone to clogging. Additionally, this simplifies maintenance and repair; as there is no need to remove the entire the entire valve from the piping for service. There are no pins or springs to fail or break, and the HDL ball valve typically comes in standard sizes so they can be replaced directly.
HDL ball check valves feature:
- Minimum maintenance and high reliability
- Non-clogging design
- Vertical or horizontal installation
- Low friction losses
- No wear under normal conditions
- Long life
- Available in ASA 125# or European DIN Flange
