Teledyne Farris Engineering 2850R-0L Relief Valve

The Teledyne Farris Engineering 2850R-0L Relief Valve is a spring-loaded safety relief valve in a 1.5 in × 2 in (inlet × outlet) configuration that automatically vents excess pressure in air, gas, steam, vapor, and compatible liquids, protecting pressurized systems such as pressure vessels, boilers, compressors, pipelines, chemical processing equipment, refineries, and power generation facilities from overpressure. Built for industrial service, the valve features a corrosion-resistant body made of 316 stainless steel or CF8M stainless steel, a carbon steel bonnet, and stainless steel trim, with a NPT threaded connection (model dependent) and a pressure rating up to 300 PSIG (series dependent). It operates as a spring-loaded relief device across a wide temperature range from -20°F to +750°F (-29°C to +399°C) depending on spring configuration, and carries ASME Section VIII certification with National Board capacity for air, gas, and steam service. The 2850R-0L is commonly used for OEM replacement, repair, retrofit, and preventive maintenance, and is used by maintenance technicians, plant engineers, and system integrators for repair, retrofit, and replacement in industrial settings; it is a common replacement option alongside TELEDYNE FARRIS 2856 Series 1.5" × 2" and 2600 Series process relief valves, with applications spanning chemical processing plants, oil and gas facilities, steam systems, compressed-air systems, and general industrial processes.
