SV80H Safety and Relief Valves

Transcription

1 age 1 of 18 I2 B ev.00 U S Safety and elief alves escription he S is a full nozzle safety and relief valve with orifices to, comply with the AI S 526, beyond others with super capacity. Suitable for gas, steam and liquid service in the oil and gas production, refining, petrochemical and process industries. Available ypes he body, bonnet, cap, nozzle, disc and spring are available in a variety of materials and selected to suit the chemical and physical characteristics of the specified process fluid available. he S has flanged connections according to AS B16.5, open or closed bonnet configurations, and can be supplied with open or packed lever and resilient seat (O ing). he valves can also be supplied with balancing or sealing metallic bellow. Applications he safety and relief valves S are designed for the effective protection of overpressure in processes or equipment, including extreme service conditions such as high outflows, high pressures, high temperatures, corrosive media, viscous liquid and high backpressures. Always consult Spirax Sarco for fluid compatibility of the construction materials. Standards and Approvals he S are designed in accordance with AS Boiler and ressure essel Code, Section III ivision 1. Capacities are certified by the ational Board of Boiler and ressure essel Inspectors. or compressible fluids and liquids, the valve can be stamped with 'U' and 'B' marks. he materials of construction and the operating pressure and temperature limits comply with AI Standard 526. hen required, the valve can be supplied with materials in compliance with AC 0175 standard for sour gas service. he S complies with the seat tightness requirements of the AI S 5. Certification A certificate of conformity is supplied with each valve including valve set pressure and hydrostatic test. aterial certification is provided in accordance with BS for all primary pressure containing parts. Optional xtras esilient seat seal O ing ard seat Stellite 6 Steam acketing ift indicator Installation and aintenance In accordance with AI 5 art 2.
