FISHER™ 289 Series 289-U-1/4-5-25 Relief Valve, 1/4 in Nominal, NPT Connection, 5 in-WC to 3 psig Pressure, Zinc Body
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.
