Fisher 289, 289A, 289H, 289HH, 289L, 289U Series Relief Valves or Backpressure Regulators

Fisher 289, 289A, 289H, 289HH, 289L, 289U Series Relief Valves or Backpressure Regulators

Fisher 289 Series relief valves are spring-loaded throttling relief valves used as downstream pressure regulators to protect the system from overpressure. A smooth throttling action minimizes pressure surges in the system during relief operation. 289 Series relief valves are ideal for low-pressure settings due to the increased sensitivity provided by a large diaphragm area. 289 Series relief valves are designed for pressure control; they are not ASME safety relief valves.
