Moog Inc., with locations throughout North and South America, has announced its new Moog Gas Control 64 K Upgrade for GE 7FA turbines, designed to extend the maintenance interval of gas control equipment from the typical 48,000 hours of operation to 64,000 hours of operation. The 64 K Upgrade Program is a hardware upgrade that offers GE turbine owners the Moog Extended Life Actuator and the Fisher Extended Life EAB Process Valve.
The Moog Extended Life Actuator Upgrade was developed to ensure the product had a long service life even in conditions with varnished, contaminated lube oil. Moog implemented the use of a contacting seal design, harder rod surface with a proprietary aerospace overlay and chrome coating for the cylinder bore. The process valve receives an upgraded live-loaded packing and a Stellite alloy sleeve in the valve stem travel area.
