Schroedahl announces that new, self-modulating TDL Automatic Recirculation Valves (ARVs)<\/a><\/strong> are now available in more than 35% lighter cast material. <\/p>\n\n\n\n

These reliable all-in-one pump protection solutions are designed to keep pumping systems in process, firefighting, refinery, power and chemical applications modulating and running smoothly, without cavitation or overheating.<\/p>\n\n\n\n

Without minimum flow, a pump can quickly suffer grave damage, causing downtime and costly repairs-but control valves for recirculation require continuous control of complex equipment, a flow measurement device, control unit, and energy supply. <\/p>\n\n\n\n

\"Recirculation
High-efficiency self-modulating pump protection valves offer reliability and\ncost savings<\/figcaption><\/figure>\n\n\n\n

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 immediately once installed. <\/p>\n\n\n\n

Schroedahl TDL Automatic Recirculation Valves combine a high-quality main line check valve and the automatic bypass control system in a durable design-developed by the inventor of automatic pump protection.<\/p>\n\n\n\n

The valves’ self-actuated integrated bypass control function ensures minimum flow rate, guarding pumps against overheating and cavitation. <\/p>\n\n\n\n

The systems provide high pump stability-with less vibration and fewer coupling or gear problems-for less downtime and lower maintenance costs. <\/p>\n\n\n\n

TDL ARVs’ modulation bypass function also offers savings for operators with reduced energy consumption for frequent partial load operation. <\/p>\n\n\n\n

Additionally, the bypass check valve prevents reverse pump flow, and allows for parallel pump installations. <\/p>\n\n\n\n

With extremely low valve hysteresis, TDL ARVs promote increased and reliable pump performance.  <\/p>\n\n\n\n

These valves are designed and built with high bypass trims size flexibility and with a wide variety of materials. <\/p>\n\n\n\n

TDL ARVs’ high bypass flow offers maximum flexibility in bypass trim sizes for pumping systems from 10- to 20-inch nominal pipe size (NPS). <\/p>\n\n\n\n

Available in EN\/DIN and ASTM materials, TDL ARVs also feature a compact cast housing design for lightweight installation.<\/p>\n","protected":false},"excerpt":{"rendered":"
