The EGV gas valve is made up of the following components:
Electrically actuated gas valves to replace OEM hydraulically and electrically actuated valves.
High driving torque and the self-cleaning nature of the valve results in low sensitivity to contamination. A limit switch is used to provide independent indication that the valve is nominally at light-off position.
TCL have developed gas valve systems for a number of gas turbines including:
These systems are calibrated to replicate the existing valve calibration and can be fitted without modifying the control system.
The gas valve is available in the following sizes:
