HBE Engineering, Inc. provides automatic recirculation valves for centrifugal pump minimum flow protection.



Automatic recirculation valves from HBE provide effective centrifugal pump protection from serious damage which can result from temperature rise or instability if operated below the required minimum flow.

HBE automatic recirculation valves are highly cost effective; combining the multiple functions of main flow check valve, flow sensing, minimum flow control, pressure reduction, and pulsation dampening into a single valve body.

Valve sizes range from 150 lb to 2500 lb ANSI rated for 1 inch to 30 inch inlet/outlet sizes. These valves are capable of handling main flow demands up to 40,000 gpm.

 
HBE DLPM Automatic Recirculation Valve

HBE Valves Featured Product #1

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.

 
HBE Anti-Flash Valve

HBE Valves: Featured Product #2

Anti-Flash Valve


The HBE Anti-Flash Valve is provided specifically to eliminate damage to the automatic recirculation valve and bypass piping due to flashing or cavitation.


The Anti-Flash valve functions as a variable orifice to assure the pressure of the downstream liquid does not fall below the vapor pressure of the fluid.

Applications which require Anti-Flash valves include boiler feed or condensate pumps which bypass back to a low or negative pressure condenser. Another need for Anti-Flash valves occurs on boiler feed pumps returning to the deaerator in peaking units. Recirculation valves in peaking units can run in a modulating state for extended periods of time with the bypass partially open. Due to the lack of piping friction, the temperature rise across the pump/valve can result in a flashing/cavitation condition.

The Anti-Flash valve is sized to produce a minimum of 30 PSIA above the vapor pressure.

Installation of the Anti-Flash valve is between flanges of the bypass piping size and ANSI rating. Installed adjacent to the condenser or deaerator tank will assure protection of the entire bypass system.
