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