HBE - Automatic Recirculation Valves
Centrifugal Pump Minimum Flow Protection
The HBE DLPM series automatic recirculation valve was developed for centrifugal pump protection, providing the following features and benefits:
Operational Dependability - the valve has only one moving part. No pilot valves or linkages are required for operation. The combination check valve/flow sensing element is guided at the top and bottom for smooth operation.
Multi-funtional Valve - provides economical and reliable protection against low flow and reverse flow conditions. The valve combines the functions of:
- Main Line Check Valve
- Flow Sensing Element
- Bypass Flow Control
- Bypass Pressure Reduction
The DLPM eliminates at least seven separate components used in a conventional system.
Self-powered - the valve operates without air or electric power and is easily installed with three connections.
