Developed for centrifugal pump protection, this unit provides the following features and benefits:
The automatic recirculating 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. The multi-functional 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.
The valve operates without air or electric power and is easily installed with three connections.
