HBE AUTOMATIC RECIRCULATION VALVE    

       The DLPM series automatic recirculation valve was develope 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-FUNCTION VALVE
     Provides economical and reliable protection against low flow and reverse flow conditions.  The valve combines the functions of  1) main line check valve 2) flow sensing the element, 3) bypass flow control, 4) 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, Petro-chemical, 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.
