Automatic Recirculation Valves
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-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.
Self-powered
- the valve operates without air or electric power and is easily installed with three connections.
Industries
The valve was developed to serve pump protection requirements of the following: power, refining, chemical, petrochemical, pharmaceutical, and HVAC.
Installations
Typical installations include: transfer, feeding, circulating, boosting, and loading pumps.
Usage
Typical uses include centrifugal pumps of ANSIAPI configuration, vertical turbine, and canned motor design.
Applications
In general any clean liquid which passes through a strainer or filter before entering the valve. Typical services include but are not limited to boiler feed water, raw water, condensate, gasoline, diesel fuel, light hydrocarbons, and feed stocks.
