Sentry Equipment 7-01137 Series TSV Thermal Shutoff Valve

Part number: 7-01137 is a self-contained, autonomous thermal shutoff valve designed to protect liquid and steam sample conditioning equipment, analyzers, and operators from high fluid temperatures. Utilizing an internal thermal actuator immersed in the sample stream, it mechanically isolates sample flow in less than five seconds when process fluid temperatures reach the calibrated trip point.

Full model name: Sentry Equipment 7-01137 Series Thermal Shutoff Valve

Application: Steam and Water Analysis Systems (SWAS), steam boiler water monitoring, condensate extraction and polishing, thermal power plants, combined heat and power facilities, desalination multi-stage flash distillation, chemical process grab sample stations, and online analyzer protection for pH, conductivity, silica, and dissolved oxygen.
