4 General General Information The API product group represents Applications Full range of spring loaded safety valves acc. to API 26 State-of-the-art design from the safety valve specialist Competitive solutions for the API market API safety valves from LESER Are designed to meet all applications which require API. Open rapidly with an overpressure of max. 10 % to the full design lift. Have a maximum blowdown of 7 % for steam/gas service and 20% for liquid service. Are developed in a close cooperation with plant engineers and service specialists. Serve for protection of processes and equipment. Are approved by all important approval organisations worldwide which ensures the worldwide applicability e.g.: European Community: CE-marking acc. to Pressure Equipment Directive (PED) 97 / 23 / EC and EN ISO USA: UV-stamp acc. to ASME Section VIII Division 1, National Board certified capacities Germany: VdTÜV approval acc. to PED, EN ISO , TÜV SV 100 and AD 2000-Merkblatt A2 Canada: Canadian Registration Number acc. to the requirements of particular provinces China: AQSIQ based on the approval acc. to ASME Section VIII Division 1 and AD 2000-Merkblatt A2 Eurasian Custom Union: Approval acc. to Eurasian Custom Union (EAC - Eurasian Conformity) Furthermore, all LESER API safety valves are designed, marked, produced and approved acc. to the requirements of the following regulations (directives, codes, rules and standards). EN ISO , EN /-2, EN 1092 Part I and II flanging ASME PTC 2, ASME-Code Sec. II, ASME B and ASME B16.- flanging, API Std. 27, API RP 76, AD 2000-Merkblatt A4, AD 2000-Merkblatt HP0 LESER API safety valves offer ultimate protection against overpressure in all applications for steam, gases and liquids. LESER s API Series safety valves present the simple safe solution for heavy duty applications, such as crude oil extraction, transportation and processing in Refineries Chemical industry Petrochemical industry Oil and gas Onshore and Offshore Vessels and piping systems Blow-down systems Storage tank farms General design features LESER s API Series covers a large variety of types, materials and options to fit any application: Design fully in accordance with API 26 for easy interchangeability Complete API 26 range: valve sizes 1" through 8", orifice D through T Materials: WCB, WCC, CF8M, WC6, LCB, LCC, and a wide range of special materials to fulfill the requirements of critical applications Special B 3 design for high back pressure applications and material requirements far beyond API Standard Fool proof design with fewer parts for built-in safety Integral cast support brackets for easy handling and safe installation Open or closed bonnet, packed or plain lifting lever or gastight cap Flanged connections according ASME and DIN guarantee a worldwide applicability One design and spring (single trim) for steam, gas and liquid applications reduces the number of spare parts and ensures low cost maintenance management. One-piece spindle reduces friction which leads to high operation accuracy Self-draining body design, avoids residues and reduces corrosion Horizontal installation 4 UV Options Special connections specified by the customer for optimised adaptation to the plant. Stellited or hardened metal sealing for longer product life Soft seat solutions for superior tightness Balanced bellows for back pressure compensation Heating jackets for applications with high viscosity fluids Any and every part can be produced in special material exactly to meet customer specification requirements
