This valve is engineered for all liquid
or gas applications in the nuclear Industry. Typical applications are feedwater
control systems, dump lines, make-up water, pilot control for large control valves, head
vent systems, and monitoring/sampling systems.
This design
uses a pilot poppet to create a pressure unbalance which assists the operation of the main
disc.
