4 Type 526 d Safety Relief s API Series LSR s API series 526 is a spring loaded pressure relief valve series, speciy designed and anufactured to API 526 and approved according to ASM (Sec. VIII, iv. 1) the Canadian CRN, the uropean P standard, the Geran A 2000-Merkblatt A2 and those of any other countries, covering requireents fro end-users, OM s and engineering copanies worldwide, thus owing iediate replaceent. LSR s API series 526 has been optiized in close cooperation with plant engineers and service specialists, siplifying design with fewer coponents for less down tie, fewer spare parts and lower aintenance costs. xtensive testing at the LSR ASM-certified test lab together with up to date anufacturing processes ensure the reliability of this state of the art product. 4 LWN
