WOODWARD 8407-515 TECJET 110 Flow Control Valve Module

• It has flexible input and can use the original equipment manufacturer (OEM)’s engine control system.

• Through the integrated CAN bus, it can achieve two-way communication with other control systems.

• It responds quickly to flow commands and can withstand large load changes without losing engine speed.

• It has a high turndown ratio, allowing one TECJET model to be used for the entire engine series (6 to 24 cylinders).

According to relevant manuals, the module is equipped with a status output pin E, which is "on" when the valve is operating normally and "off" when a warning or error occurs. Pin J is a discrete/RS232 common terminal. The inlet and outlet pipelines of the valve must comply with the ANSI/ISA-S75.02 standard. Generally, the minimum length of the inlet pipeline can be 6 times the pipe diameter, and the minimum length of the outlet pipeline can be 2 times the pipe diameter, with negligible impact on the valve’s metering accuracy. In addition, the module can be switched to a low-power state via a key switch (input current <200mA): the valve works normally when receiving a high signal (connected to the positive pole of the power supply) and enters the low-power state when receiving a low signal (connected to the negative pole of the power supply or open circuit).

• Power Energy Field: In power plants, it can be used in gas turbine and steam turbine systems to precisely control fuel or gas flow, ensuring efficient combustion, improving power generation efficiency, and reducing emissions. For example, in some gas-steam combined cycle power plants fueled by natural gas, the module can accurately adjust the natural gas flow according to power generation load requirements, keeping the gas turbine in optimal operating condition and thereby improving the energy efficiency of the entire power plant.
• Industrial Production Field: In the chemical industry and petrochemical production, it is often used to control the flow of liquid chemicals or gases to ensure stable production processes and reaction safety. For instance, in the ammonia synthesis process, it can precisely control the flow of gases such as hydrogen and nitrogen, ensuring chemical reactions proceed in the set proportion and improving the output and quality of ammonia. In the oil refining process, it can accurately control the flow of various oils and gases to ensure the stable operation of refining equipment.
• Transportation Field: It can be matched with Jichai 190 gas engines (12V190 and 16V190 generator sets) as their accessories to provide stable power support for vehicles, ships, etc. For example, on ships using gas engines, the module can precisely control gas flow, ensuring stable power output of the engine to meet the power requirements of ship navigation.
• Aerospace Field: Precise flow control is crucial to system performance in aero-engines and aerospace systems. This flow control valve module can be used to regulate fuel flow, ensuring the engine operates stably under various load and environmental conditions. For example, in an aircraft’s auxiliary power unit (APU), precise control of fuel flow ensures reliable startup and operation of the APU, providing air and power for the aircraft.
• Other Fields: In industrial automated fluid systems, such as aeration systems in sewage treatment plants, it can precisely control air flow according to sewage quality and treatment process requirements to improve sewage treatment efficiency. In some experimental equipment requiring precise gas flow control (e.g., material performance testing equipment, environmental simulation experimental equipment), the module also plays an important role by providing stable and precise gas flow for experiments, ensuring the accuracy and reliability of experimental results.
