■ A family of high-pressure casings
■ A family of extraction/admission valve gears and associated pattern
sections
■ A complete line of single- and double-flow exhaust casings for both
condensing and noncondensing applications
■ Microprocessor-based control systems from simple, single-variable
controllers to triple-redundant, fully integrated monitoring and
multivariable control function systems
■ Structured steam and oil piping brought out to standard customer
interface points
■ A customized steam path consistent with overall thermodynamic
requirements
