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.
[Compressor bleed valve(high/middle/low pressure)]
In order to stop the compressor for safety, these valves open and discharge large-volume high temperature air to the atmosphere when gas turbine stops.
[Lube oil pressure regulating valve]
The valve controls pressure of lube oil which supplied to bearing seal part or auxiliary equipment. And this is operated by self-actuation and high response.
[Lube oil temperature control valve]
The valve controls pressure of lube oil.
