U€L+® PRESSURE-RELIEF VALVES SMFN-7000 SMF-7000 SMF*-7000 SU-7000 PRESSURE RELIEF Valve Type-SMFN-7000, SMF-7000, SMF*-7000& SU-7000 This product range is mainly used forThermal Relief application but thanks to the certified coefficient of discharge for gas and liquid it can be used also for pressure relieving application. Types SMF-7000 covers the application where users have preference for screwed connection. These valves are available with inlet sizes from V2” to 1” and pressure from 0.8 Bar to 400 Bar for Gas & up to 1500 Bar for Liquid in various material combinations. Type SU-7000 has...

RELIEVING TEMPERATURE COLD DIFFERENTIAL TEST PRESSURE (SPRING SETTING) RANGE COLD DIFFERENTIAL TEST PRESSURE TOLERANCE The tolerances on the cold differential test pressure are the following: Up to 3,7bar ±4% or ±0,04 barwhichever is greater over21 bar ± 1% or 0,7 barwhichever is greater MINIMUM COLD DIFFERENTIAL TEST PRESSURE (SPRING SETTING) The minimum setting pressure are the following: SEATTIGHTNESS (Nozzle-Disc) Seat tightness at ambient temperature is performed according to API-527 by raising the pressure to 90% of the set pressure (for tight seals to 95%) and checking that the...

BELLOWS TYPE SAFETY VALVES Series SMF*7000; SU-7000 valves with Orifice “f” may be supplied with balancing and separation bellows Valves of this type are used to: a) Prevent set pressure variations in case of variable back pressure; b) Separate the disc guide and all components inside the bonnet from the process fluid when the latter is corrosive, viscous or likely to leave deposits, incrustations or to crystallize. The bellows are designed to afford the greatest possible flexibility, greatest mechanical strength and the best possible balancing. CLASSIFICATION The selection UKL-AST of...

Reseating pressure (of a safety valve) The value of the inlet static pressure at which the disc re-establishes contactwiththeseatoratwhich the lift becomes zero. Relieving pressure The pressure used for the sizing of a safety valve which is £ set pressure + overpressure. Setpressure The predetermined pressure at which a safety valve under operating conditions commences to open. It is the gauge pressure measured at the valve inlet at which the pressure forces tending to open the valve for the specific service conditions are in equilibrium with the forces retaining the valve discon its...
