Product catalog summary
Overview: This document outlines the specifications and operational characteristics of the 130 series safety and relief valves, detailing materials, temperature and pressure ranges, certifications, and flow rates.
Specifications:
  • Temperature Range: Operates from -196°C to +537°C, depending on material and design.
  • Materials: Constructed from cast iron, carbon steel, and stainless steel, adhering to ASTM and EN standards.
  • Pressure Ratings: Inlet and outlet connections rated from EN PN 16 to EN PN 40 and ASME CL 150, with specific pressure settings for various applications.
Operating Characteristics:
  • Set Pressure Range: Designed for pressures from 0.20 to 40 barg.
  • Overpressure and Blowdown: Overpressure set at +10% of p if p ≥1 bar or +0.1 bar if p < 1 bar. Blowdown is -10% of p if p ≥1 bar or -0.1 bar if p < 1 bar.
  • Back Pressure: Specifies maximum allowable built-up and superimposed back pressure, with recommendations to consult the Technical Department for specific conditions.
Certifications and Connections:
  • Certified under PED, ATEX, GOST, and RINA standards.
  • Flanged connections available in EN and ANSI standards, with customizations possible upon request.
Flow Rates:
  • Flow rates for water, air, and steam at various set pressures, with detailed tables illustrating discharge capacities.
Additional Notes:
  • Relief valves in the 130 series are identified by an 'R' after the model number, with similar material and operational limits as safety valves.
  • Customizations are possible upon request and approval by Besa® Technical Department.
Flow Rate Data: Detailed flow rate data for air, steam, and water at 25°C, measured in kg/h, with specifications for different diameters and calculation methods.
Procedures: Flow rates determined using specific formulas, with linear interpolation for intermediate values. BESA® verifies fluid mechanical sizing of each safety valve.
Standards and Norms: Calculations adhere to EN 4126-1 standards, ensuring consistency and reliability.
Recommendations: BESA® reserves the right to perform fluid dynamic sizing for each safety valve, providing calculated flow rates in relevant documents.
Key Data: Extensive tables of flow rates for air, steam, and water, crucial for understanding valve performance under various conditions.

Note Valvole di sfforo Le valvole della serie 130 sono disponibili anche nella versione valvole di sfforo. Le Valvole di sfforo, identiffcate dalla lettera R posta accanto al numero identiffcante il modello, si caratterizzano come accessori (dispositivi) a pressione aventi funzione di servizio. I materiali di costruzione, le dimensioni ed i limiti di utilizzo secondo il rapporto pressione/ temperatura delle valvole di sfforo, sono gli stessi validi per le valvole di sicurezza della Serie 130. Alcuni dati riportati nella presente pagina possono variare su specifica richiesta, previa analisi e approvazione delle funzioni competenti di Besa® S.pA LEGENDA: p=set pressure (barg) pb= backpressure (barg) Note Relief Valves: 130 Series Safety valves are also available as Relief valves. Relief valves, identified by the letter R after the type number, are devices with an operational function, having pressure-bearing housings. Materials, dimensions and application limits depending on Pressure/Temperature ratio for Relief Valves are the same of Safety Valves 130 Series. some information given on these pages can be changed upon specific requests, after besa® qualified office approval.
