✦ Synopsis

Narvik-Yarway has extended its Series 9200 range of automatic recirculation control valves to include larger sizes. The ARC range is designed to provide the highest level of protection for centrifugal pumps against the damage of overheating caused by low flows.

Completely self-contained, the Series 9200 is an integrated system which functions as a flow sensing device, spring-loaded check valve, recirculation control valve and staged pressure let-down unit. This single system provides considerable cost and energy savings over the more traditional and complex multi-instrument flow control loops. For optimum operating efficiency, the valve's CONTACT
