Steam-Conditioning Valve
Full control in steam conditioning
ARCA steam-conditioning valves are customized in line with your specific operating conditions. A wide range of designs and materials – from cast globe-style housings to forged angle-style valves – are available to meet all pressure and temperature requirements.
ARCA control valves optimize efficiency and enable cost-effective operation in small plants and large-scale power-generation facilities.
ARCA steam-conditioning valves integrate sound-reduction measures such as perforated plugs and seat rings with graduated control to minimize the impact of sound emissions on humans and the environment. We can even dimension a silencer system that en compasses the condenser of your plant.
