NAKAKITA SEISAKUSHO CO., LTD.
VALVES FOR GAS TURBINE POWER PLANTS
NAKAKITA offers control valves, cylinder valves and
butterfly valves used for gas turbine power generation plants and gas turbine
combined cycle power plant (GTCC).
NAKAKITA’s valves in Gas Turbine Power Plants
Control Valves
Fuel gas (oil) flow control valve
Fuel gas (oil) pressure control valve
Fuel gas (oil) pressure control valve
One of the most important valves which controls the fuel gas to be supplied to the gas turbine.
From a small flow rate at the time of the gas turbine ignition up to 100% load operation, a wide range can be controlled.
Electric or hydraulic servo actuators have high-response and high-precision control to shut off the fuel rapidly by the emergency shut-off signal.

with hydraulic actuator
Pure water control valves for NOx control
This valve has high accuracy for flow rate to supply injection of pure water to reduce NOx of the combustion gas.
Fuel gas temperature control valve
This valve supplies fuel gas in the suitable temperature condition by mixing ambient-temperature fuel gas and a heated fuel gas.
Lube oil temperature control valve
This valve is used to control the temperature of lubricant oil supply to bearings of gas turbines and other equipment.
with pneumatic actuator
[Other applications] FUEL GAS MAIN PRESSURE CONTROL VALVE, FUEL GAS PILOT PRESSURE CONTROL VALVE, FUEL GAS TOPHAT PRESSURE CONTROL VALVE, FUEL GAS MAIN FLOW CONTROL VALVE, FUEL GAS PILOT FLOW CONTROL VALVE FUEL GAS TOPHAT FLOW CONTROL VALVE, FUEL OIL SUPPLY PRESSURE CONTROL VALVE, FUEL OIL MAIN PRESSURE CONTROL VALVE, FUEL OIL PILOT PRESSURE CONTROL VALVE, FUEL OIL MAIN FLOW CONTROL VAVLE, FUEL OIL PILOT FLOW CONTROL VALVE, MAIN WATER INJECTION FLOW CONTROL VALVE, PILOT WATER INJECTION FLOW CONTROL VALVE, PURGE AIR PRESSURE CONTROL VALVE, LUBE OIL TEMPERATURE CONTROL VALVE
On-Off Valves
Fuel gas (oil) nozzle sweep supply/vent valve
In order to prevent clogging of the fuel nozzle, this valve is designed for sequential operation as a hot air supply valve and a relief valve.
Butterfly Valves
Compressor bleed valve (high/middle/low pressure)
To safely stop the compressor, this valve bleeds a large volume of high temperature and high pressure air from the compressor.
[Other applications] COOLER TEMPERATURE CONTROL VALVE, COMPRESSURE HIGH PRESSURE BLEED VALVE, COMPRESSOR MIDDLE PRESSURE BLEED VALVE, COMPRESSOR LOW PRESSURE BLEED VALVE
Regulator Valves
Lube oil pressure regulating valve
This valve is used to control pressure of lubricant oil supply to bearings of gas turbine and auxiliary equipment. Self-actuation and high response.
Special Valves
Fuel oil stop valve
16-20 valve bodies are operated by one actuator to shut off the fuel supply at the inlet of the fuel oil nozzles. Compact and unique valves.
