If your gas turbine relies on older valves, we understand why you may be hesitant to move your maintenance schedule from overhauling to replacement. New valves are expensive and changes to system piping may upset a working system.

However, if you have Woodward gas valves, the GS40 and GS50 can provide a significant upgrade for your system's safety and reliability, also decreasing your maintenance frequency.

Here’s reasons to switch:

Enhanced Torque Capability: The new gearless direct-drive design delivers significantly more torque, ensuring reliable operation in demanding conditions. The GS40 offers 6 times the torque capability of the GS6, while the GS50 offers 4 times that of the GS16. This significant performance increase over legacy valves allows valves to deliver even in the most challenging applications.

Longer Service Intervals: Increased overhaul cycle from 50,000 to 64,000 hours.

Integrated DVP driver: The GS40 and GS50 eliminate the need for a separate DVP driver by integrating the DVP directly into the valve, simplifying system wiring and leaving more space in your control cabinet. This integrated driver includes redundant signal conditioning, advanced fault detection, and customizable failure management options.

Fail-safe Return Spring: An additional built-in fail-safe return spring automatically returns the valve to a closed position during shutdown.

No More Hydraulics: Hydraulic fluids can be sensitive to temperature changes and may cause unexpected wear or damage to valves. The GS40 and GS50 are electric actuated, meaning your turbine or engine can start or stop when you need it to.

Greater Accuracy: GS40 and 50 include redundant resolvers, allowing for more accurate valve positioning every time.

Drop-In Solution: The GS50 can replace 3103 and GS16 valves without modifying system piping in most applications. The GS40 similarly acts as a replacement for the GS6.

Resilient to Gas Impurities and Debris: The new metering valves are designed to be self-cleaning, making the valve great in dirty situations like wellhead gas.
