SCHROEDAHL announces self-modulating TDL ARVs

SCHROEDAHL, a CIRCOR International brand has announced that new, self-modulating TDL Automatic Recirculation Valves (ARVs) are now available in cast material that is more than 35% lighter.

The all-in-one pump protection solutions are designed to keep pumping systems running smoothly in firefighting, refinery, power and chemical applications without cavitation or overheating.

Unlike control valve packages, the self-operated flow-sensitive Schroedahl TDL Automatic Recirculation Valves operate without a separate power supply or any control system and begin protection as soon as they are installed.

The valves combine a high-quality main line check valve and the automatic bypass control system in a new, durable design. The valves’ self-actuated integrated bypass control function ensures minimum flow rate, guarding pumps against overheating and cavitation. The systems provide high pump stability with less vibration and fewer coupling or gear problems. TDL ARVs’ modulation bypass function also offers savings for operators with reduced energy consumption for frequent partial load operation.

Additionally, the bypass check valve prevents reverse pump flow, and allows for parallel pump installations.
