API meets all requirements of the API 526 norm and includes the entire orifice D to T product range.
API 526 is a purchase specification in which the nominal diameters, flange pressure ratings, centre to face dimensions, flow areas, body and spring materials and their service limits are stipulated for "API safety valves"
API safety valves are used worldwide in the petrochemical industry, both on- and off-shore. These applications are characterised by standardised plants, blow-down systems and long pipework sections. The capacities of API safety valves are relatively low in relation to their nominal diameters.
The LESER type 526 combines the requirements of the API standards and the ASME Code with the tried and tested service reliability of the LESER range.
