New High Performance 441 XXL Cast Design

The new High Performance 441 XXL series in cast design has passed the initial sample test, the tightness test and the trial assembly successfully. As early as September 2021, the first 441 XXL cast design safety valves initially in nominal size DN 250 x DN 350 will be available for order.

The LESER customer advantages compared to the welded version are the following:

  • Shorter delivery times
  • Lower list prices 
  • Elimination of welding-relevant tests on the valve body
