Fuel gas(oil) flow control valve / pressure control valve］
They are one of core valves for Gas turbine and they control the fuel supplied to a gas turbine. It has tight shut-off ability and wide range control which flow rate is at the time of gas turbine ignition to 100% load operation. This valve was operated by E/H servo control system and high response and a highly precise movement is performed.
［Pure water control valve sfor NOx control］
To reduce NOx in exhaust gas, this valve supplies pure water to the gas turbine. And also highly precise movement is performed.
［Fuel oil stop valve］
The valve from which fuel oil is insulated at the nozzle inlet side. 16-20 valve bodies (same number as the nozzle) are made the structure operated by 1 actuator.
［Fuel gas(oil) nozzle sweep supply/vent valve］
The valve supplies to a nozzle with high temperature air for stuff prevention of fuel nozzles. Valves have actuator parts which are designed so that an escape valve might move sequentially.
［Fuel gas temperature control valve］
This is the valve which makes suitable temperature fuel gas by mixing heated gas and low temperature gas.
