Jewellok Pressure Regulator

A Jewellok pressure regulator is a valve that controls the pressure of a fluid to a desired value, using negative feedback from the controlled pressure. Regulators are used for gases and liquids, and can be an integral device with a pressure setting, a restrictor and a sensor all in the one body, or consist of a separate pressure sensor, controller and flow valve.

Jewellok Pressure And Fluid Control Calibrated to Your Application

Maintaining pressure and flow requirements and safe fluid measurement are critical objectives in analytical & calibration labs, R&D, testing, and manufacturing in energy, chemical production, aerospace, automotive, hydrogen, semiconductor fabrication, and many other industries. Whatever your application, depend on Emerson for precise, reliable, standard & custom-engineered pressure regulators and instrumentation valves — as well as our industry expertise and global support.
