Loyalty by transformation. With almost 200 years of experience, LESER ranks among the pioneers of mechanical engineering in Germany. The company started in Germany in 1818 as a brass foundry and developed a product portfolio of components of mechanical equipment and machines during the "industrial revolution".

In 1885 the company developed its first safety valve for the protection of steam boilers. Even at that early date, LESER products were working for the safety of man and the environment. Since the 1970"s LESER has specialized only in safety valves.

01/01 LWN 487.71-E Series 810 and 820 Overview LESER Pilot Operated Safety Valve (POSV) LESER Pilot Operated Safety Valves (POSVs) are designed according to the API 526 standard. The full range of sizes from 1" x 2" up to 8" x 10" (DN 25 – DN 200) with all orifices from D – T is available for pressure ratings up to pressure class 600 x 150. Beyond API 526, LESER offers so-called Extra Orifices (also known als Full Port or Full Bore nozzles, see page 01/09). The Extra Orifices provide maximum capacity in relation to valve size. In addition, LESER POSVs come in two different functional...

Product Description Series 810 and 820 Specifications and Approvals The LESER Pilot Operated Safety Valve (POSV) comprises the POSV main valve and a pilot valve based on either the Pop Action (Series 810) or the Modulate Action (Series 820) designs. The table below shows their common and their specific features. Specification at a glance Product Description 1) The possible flange pressure ratings depend on the size of the valve.

01/03 LWN 487.71-E Product Description Good Reasons for the LESER Pilot Operated Safety Valve Pilot operated safety valves have been a proven technology for many decades especially in ASME oriented regions. However, some of the older designs show potential for improvement in areas like external tubing, capacity and delivery times. Based on customer feed back and extended research and using Computational Fluid Dynamics (CFD), Rapid Prototyping and one of the most modern factories for safety valves, LESER has developed the latest POSV on the market. The new LESER POSV offers unique benefits...

Applications – Functional Areas Across applications, there are four main functional requirements covered by the LESER Pilot Operated Safety Valve (POSV). High Back Pressure Applications • LESER POSVs can be operated in applications with a back pressure ratio (i.e. a ratio of back pressure / set pressure) of up to 70%. Spring loaded safety valves can be typically used up to 50% of back pressure. • The absolute maximum back pressure is determined by the pressure class of the main valve outlet. Typically, LESER POSVs can be used for much higher back pressures than spring loaded safety valves....

Product Description LWN 487.71-E 01/06 Applications – Examples Compressors in Gas Main Systems Pressure relief devices in these applications must allow for high operating pressures in relation to set pressure, which are required for efficient gas transport. Additionally, compressor vibrations put through requirements on the tightness of the safety valve. LESER Series 810 and 820 POSVs offer an ideal solution for these conditions because: • they enable highest possible operating pressure to set pressure ratios facilitating maximum energy density of transport medium • they are not susceptible...

Product Description 01/07 LWN 487.71-E Sour Gas Applications (NACE) LESER Pilot Operated Safety Valves (POSVs) are available for sour gas (H2S) service. Regulatory Requirements The material requirements for hydrogen sulfide (H2S) service (sour gas service) are specified in the NACE standards, MR0175/ISO 15156 (Upstream processes), and MR0103 (Downstream processes). Since the body of the pilot valve is manufactured from stainless steel, only the spring in the pilot valve of the Series 810 Pop Action POSV and the dome spring in the main valve need to be replaced for compliance with these NACE...
