SKINNER Circle 41 on Reader Service Card Introduced in 1984 by Skinner Engine Company's Power Division, Erie, Pa., the first hydraulically actuated governor valve control for controlling steam turbine speed has performed better than initial expectations.

The company reports that data gathered from dozens of installations reveal a record of unsurpassed economy, adaptability, and dependability.

The Skinner SPR™ System, powered by the Woodward TG-13 constant- speed governor, requires fewer adjustments following initial start-up than comparable governor valve controls because it is a closed system with no mechanical wear points. It instantly corrects variations in preset turbine speed without the "hunting" for correct speed found in standard mechanical linkage controls.

The SPR system is free from the shock loads and backlashes that can cause the levers, arms, and pins of mechanical systems to weaken or break prematurely. The system's elimination of speed correction turbulence also helps extend the life of the governor valve, cage, and stem, and the absence of any mechanical linkage reduces maintenance costs.

At slight underspeed or overspeed conditions, the movement of a rotary actuator in the SPR system initiates a chain of events in the hydraulic system that opens or closes the steam inlet to provide immediate response to speed variations.

The SPR also produces a substantial increase in the power available at the governor valve.

The system is a retrofit package made for all popular types of singlestage steam turbines. It is available in configurations for Coppus, Elliott, and Terry turbines, with others available upon application.

TELEFLEX Circle 47 on Reader Service Card The Remote Mechanical Valve Actuator (RMVA) developed by the Remote Actuation System Group of Teleflex, Inc., King of Prussia, Pa., eliminates problems associated with current methods of remote valve actuation.

The Teleflex RMVA system is based on a simple tension-tension, closed-loop actuating concept. Helical cable, operating in a conduit, converts rotary to linear motion and then back to rotary. The flexibility of the conduit allows the system to make bends without the use of expensive gear boxes. It also eliminates the need for costly universal joints by allowing the system to be routed without concern for critical alignments.

This simplistic design eliminates the need for regular maintenance and provides a significant cost savings compared with the complex reach rod and flexible shafting applications.

Designed to survive the harshest environments, RMVA uses materials and SermeTel coatings that are extremely corrosion-resistant. The system has been approved for use on all U.S. Navy surface vessels, and is certified by the American Bureau of Shipping. The system has been in use on Navy ships for more than two years and continues to perform reliably.
