1 Series Thermal Relief Safety Valves Spring loaded Thermal Relief Safety Valves, manufacturers standard Medium and high pressure Applications The Sempell series provides a complete and comprehensive range of safety valves for all industrial applications. Features and Benefits Thermal expansion to API 520 Certified capacity figures in accordance with ASME VIII for Air, Liquid and Steam Replaceable nozzle Rugged construction Scope The Sempell Series are spring loaded, fixed blowdown, nominal capacity safety valves for use on vapour, gas and liquid overpressure protection. They are complementary to the A series. The range is available with threaded, flanged, socket weld or butt weld connections, or in various combinations. NPT and ASME-ANSI connections are standard offerings but ends can be machined to any standard of choice. Performance The performance of the series is certified and authorised by independent, international authorities UV stamp (certified according to the rules of the ASME code, section VIII.) other approvals. Technical data Conventional Metal or soft seated Temperature range : -268 C to +399 C Pressure limits : 344 barg Steam : 68.9 barg Sizes : 1/2 x 1 to 2 x 2 Orifice : to 3.245cm 2 Tyco reserves the right to change the content without notice SEMDR-0056-EN-0312
