The deaerator pegging steam valve provides steam
that gives positive pressure to the deaerator or
IP and LP drum to prevent air from being drawn into
the feedwater system during plant start up. Steam
from this valve also heats the feedwater. Steam may
come from a low pressure package boiler or the plant
main steam line.
Fisher pegging steam valves ensure pressure
reduction and noise attenuation, regardless of
steam source.
Steam Seal Regulator Valve
Steam seal regulator systems have several valves that
experience varying conditions. The steam seal feed
valve takes full main steam pressure down to 0.2 - 0.3
bar (3-5 psig). This extreme pressure drop presents
several challenges including noise and vibration.
Fisher steam seal regulator valves contain noise
abatement trim to combat to these tough challenges.
