Fisher controls regulator 289H-49,
Fisher Controls:289H-49 Diaphragm Relief Valve, NIB, excellent condition.
The Type 289H is installed between large second-stage regulators like the S302 or S202 and the burner to provide high capacity relief. The large diaphragm in these valves gives extremely sensitive operation.
The 289 Series pressure relief valves are throttling relief valves used downstream of pressure regulators to protect the downstream system from overpressure. These relief valves can be used for natural gas, air, propane, or other noncorrosive, gas-flow service.
