Most mills need to accommodate a variety of steam pressure requirements for the various processes in the mill. Steam from the power and
recovery boilers supply high pressure and temperature steam to the high pressure header, and can be staged down to accommodate the
pressures needed at the other headers.
Pressure reduction between headers can be achieved through the use of pressure reducing valves (PRV) or a steam turbine. These valves are
exposed to high pressure and temperature steam, high ambient temperatures, severe vibration, and high levels of noise.
Main Steam Pressure Reduction
n HIGH PRESSURE CAPABILITIES Rugged design and valve options allow for a
multitude of pressure class ratings.
n HIGH TEMPERATURE OPTIONS Valve options provide high temperature
capabilities that also reduce vibration,
mechanical noise, and maintain valve plug stability.
n NOISE REDUCTION Available trim technologies to ensure the
safety of personnel and meeting regulatory
requirements.
n TIGHT SHUTOFF Advanced sealing technology provides correct
shutoff and extends valve’s service life.
n EASE OF MAINTENANCE Valve can remain in pipeline during removal of
trim parts for inspection or maintenance.
n POSITIONER FEEDBACK Linkage-less and non-contact feedback
improves reliability in high vibration.
