The Young & Franklin 3010 Series sonic flow gas control valves (GCVs) are electro-mechanically actuated...
Young & Franklin has been featured alongside other manufacturers in Power Engineering International’s Volume 25, Issue 2, where the company discusses its valves and actuators.
The piece is called, "Valve & Actuators: Risks and Oppurtunities". Here is an excerpt:
Francis Bouziden, sales and marketing manager at large-frame gas turbine valve and actuator manufacturer Young & Franklin (Y&F), points to a turbine-specific issue: he says the hydraulic system is the number one risk to any valve or actuator, and its care and maintenance represent an "ongoing source of many owners’ headaches".
"One leaky fitting or one stuck servo can cause a turbine trip or failed start," he explains, and for a plant that needs to ramp up quickly, "both of these issues can be extremely costly. Even worse, hydraulic leaks cause environmental issues and there have been reported fires as a result of hydraulic oil spraying on the turbine."
Bouziden notes that turbine technicians have traditionally focused on managing and treating the effects of hydraulic system issues such as deposits on the valve caused by lubricant degradation, called varnish and sludge. Steps such as filtration, flushing and specialized oils "are all trying to address one part of a system that has many opportunities for failure," he says. Instead, "the primary cause of the issue is that lube oil is being tasked with double duty: both lubrication and control. While this may have been an acceptable solution for early turbine designs, it is clearly not acceptable for the modern gas turbine."
