SV81HSafety and Relief Valve

DescriptionThe SV81H have fixed blowdown.No blowdown adjustment required when setting or testing the valve.It is designed for short blowdown on all medias.

Available TypesThe 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 SV81H has screwed connections (NPT) according to ASME B1.20.1, can be supplied with open or packed lever, resilient seat (O’Ring) and test lever. The SV81H can also be supplied with flanged and welded connections.

ApplicationsThe safety and relief valves SV81H 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 and viscous liquid. Always consult Spirax Sarco for fluid compatibility of the construction materials.

Standards and ApprovalsThe SV81H 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.Standard construction includes 304 or 316 stainless steel body, trim and carbon steel bonnet.When required, the valve can be supplied with materials in compliancewith NACE MR-01-75 standard for sour gas service.The SV81H complies with the seat tightness requirements of theAPI STD 527.

CertificationA certificate of conformity is supplied with each valve including valveset pressure and hydrostatic test. Material certification is provided in accordance with BS-EN 10204 Type 2.3, for all primary pressure containing parts.

Optional ExtrasResilient seat seal – O’RingHard seat – Stellite 6Lift indicator

Purchase InformationFor the correct sizing and selection of the SV81H, 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.
