The RTK Discharge and Pump Protection Control Valve (photo) provides a suitable solution for all industrial processes that incorporate pumps, such as condensate pumps, boiler feedwater pumps or low-pressure centrifugal pumps. The RTK control valve works as two valves in one: it brings together a pump-protection recirculation valve and a control valve. In this capacity, the valve not only cuts costs, but also increases the life span of pumps by both regulating the main flow and the recirculation flow with a single valve. The recirculation feature provides an inline-adjustable recirculation port, which allows users to control the valve inline while the pump is working. — Circor International, Inc., Burlington, Mass.
