PRESSURE RELIEF Valve Type-SV-200-LP/SV-200- 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 SV-200 covers the application where users have preference for screwed connection. These valves are available with inlet sizes from V2" to 1" and Liquid in various material combinations. Type SV-300 has flanged end connections with an integral cast - Safety Valve & Control Valve Division

BELLOWS TYPE SAFETY VALVES Series SV-200-HP; SV-300 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 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 The bellows are designed to afford the greatest possible flexibility, greatest mechanical strength and the best possible balancing. The selection UKL-AST of safety relief valves is simplified by an...

STANDARD MATERIALS Remark: On request the valves can be supplied partially or completely in AISI316 - Monel - Hastelloy - Aluminum etc. DEFINITIONS (abstract from EN ISO 4126-1) The actual travel of the valve disc away from the closed position. Flow area The minimum cross-sectional flow area (but not the curtain area) between inlet and seat which is used to calculate the theoretical flow capacity, with no deduction for any obstruction. The value of actual flowing capacity (from tests) divided by the theoretical flowing capacity (from calculation). Built-up backpressure The pressure existing...

Reseating pressure (of a safety valve) The value of the inlet static pressure at which the disc re-establishes contact with the seat or at which the lift becomes zero. Relieving pressure The pressure used for the sizing of a safety valve which is s set 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 disc on its seat. Blowdown (of a safety valve)...
