SV80H Safety and Relief Valves
TI-D344-02
BR Rev.02
Description The SV80H is a full nozzle safety and relief valve with orifices D to T, comply with the API STD 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 Types The 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. The SV80H has flanged connections according to ASME B16.5, open or closed bonnet configurations, and can be supplied with open or packed lever and resilient seat (O’Ring). The valves can also be supplied with balancing or sealing metallic bellow.
Applications The safety and relief valves SV80H 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 The SV80H are designed in accordance with ASME Boiler and Pressure Vessel Code, Section VIII Division 1. Capacities are certified by the National Board of Boiler and Pressure Vessel Inspectors. For compressible fluids and liquids, the valve can be stamped with 'UV' and 'NB' marks.
The materials of construction and the operating pressure and temperature limits comply with API Standard 526. When required, the valve can be supplied with materials in compliance with NACE MR-01-75 standard for sour gas service. The SV80H complies with the seat tightness requirements of the API STD 527.
Certification A certificate of conformity is supplied with each valve including valveset pressure and hydrostatic test. Material certification is provided in accordance with BS-EN 10204 3.1 for all primary pressure containing parts.
Optional Extras Resilient seat seal – O’Ring Hard seat – Stellite 6Steam Jacketing Lift indicator
Installation and Maintenance In accordance with API RP 520 Part 2. It covers recommended
piping practices, calculation of reaction forces and precautions on
pre-installation handling. Please refer to the last revision of the IM-D344-02 for full details.

Purchase Information For the correct sizing and selection of the SV80H, the following information is necessary:
1) Fluid 2) Required capacity (flow) 3) Operation pressure and Set pressure 4) Operating temperature and Opening temperature 5) Backpressure 6) Overpressure 7) Viscosty and Specific Gravity (Liquid)8) Molecular Weight (Gases)
Spirax Sarco has a computer sizing program (PSV Calc ) which performs sizing and selection functions. Additionally, it will select materials, configure the complete valve and provide a data sheet.
