Fisher EZR Series Relief Valve or Backpressure Regulator

توضیحات

 آتصا | ابزاردقیق و اتوماسیون
The Type EZR pilot-operated, pressure relief valve or backpressure regulator is typically used in city gate and district stations as a relief valve for overpressure protection or in commercial and industrial applications as a backpressure regulator. The diaphragm and plug assembly moves in response to the pilot loading pressure to control upstream system pressure. Force from the main spring provides downward pressure to keep the main valve tightly shut off.
A pressure relief valve is a throttling pressure control device that opens and closes to ensure the inlet pressure does not rise above a predetermined pressure. Fisher® relief valves cannot be used as ASME safety relief valves. A backpressure regulator is a device that controls and responds to changes in the upstream pressure. It functions the same as a relief valve in that it opens on increasing upstream pressure.
