TESCOM 54-3500 two-stage hydraulic back pressure
regulator reduces the controlled inlet pressure in 2
steps. The integrated second stage is self loading and
adjusts itself to 50% of the inlet pressure, regardless if
the unit is spring, air or dome loaded. This reduction
of differential pressure per stage significantly reduces
the destructive force of erosion and cavitation. A
wide range of soft goods and valve trim materials,
including ceramic option, allow for media specific
regulator selection.
