This valve is engineered for liquid or gas
applications in the nuclear Industry. Typical applications are feedwater control
systems, dump lines, make-up water, miscellaneous process systems, N2 systems,
monitoring and sampling systems.
Extreme reliability is
inherent due to rugged design, simplicity of operation, and a minimum number of moving
parts. Isolation standoffs prevent excessive heat transfer to the solenoid
operator. Internal parts are contoured to retard buildup of contamination and
sludge. Compact, lightweight design provides excellent resistance to seismic
vibration and shock. A completely enclosed and encapsulated coil ensures continuous
operation during a LOCA event.
This design uses a balanced disc (poppet) which permits
bi-directional flow and tight sealing in both flow directions.
