Leser has developed a complete range of safety valves within the API 526 design standards.
Safety valves are the last mechanical devices to protect your installation. An overpressure in your system must always be released safely in order to prevent explosions or other disasters. Due to the unique design of the inner parts the Leser API 526 offers you more operational reliability, longer service life and – because of fewer components - it saves you on maintenance.
Leser offers the complete range with valve sizes from 1”x 2” to 8”x 10” in many ratings such as Class 150 x 150, 300 x 150 up to 2500 x 300 and from orifice sizes D to T. Leser goes even beyond the API-526 range by offering many prevalent combinations outside the standard flange ratings - such as 300 x 300 or 600 x 300.
If you have applications with harsh media or a corrosive environment, then safety valves can be supplied in various special materials. Leser has come up with a unique system for this so that you only need to purchase those components made of special material that are required for your respective application, such as the nozzle only or complete trim. The body can then be supplied in a suitable standard material.
