Designed to meet all industrial applications.
LESER High Performance Safety Valves are designed to meet all industrial applications, open rapidly with an overpressure of 5 % to the full design lift, and are used particularly for vapor’s and gases where the maximum mass flow has to be discharged rapidly. They have a maximum blowdown of minus 10 % for steam/gas service and minus 20 % for liquid service. They are one of the best selling spring loaded safety valve worldwide. Developed in a close cooperation with plant engineers and service specialists, they serve for protection of processes and equipment.

High efficiency.
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 2500 x 6001). Beyond API 526, LESER offers so-called Extra Orifices (also known as Full Port or Full Bore nozzles). The Extra Orifices provide maximum capacity in relation to valve size. In addition, LESER POSVs come in two different functional designs, i.e. Pop Action (Series 810) and Modulate Action (Series 820). These designs determine the POSVs operating characteristics.
