HBE Engineering | Automatic Recirculation Valves (DLPM Series)

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.

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 ANSI\API 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.
