Functional Features:​ Rotary plate metering structure with single moving part for high reliability; non-contact position sensor eliminates mechanical wear; rare-earth permanent magnet actuator delivers high torque density and fast response; remote shutdown command input supports emergency stop; valve/driver fault output enables system diagnostics.

Application Scenarios:​ Liquid fuel control for gas turbine generator sets, industrial mechanical drive, and marine propulsion systems. Handles diesel, kerosene, gasoline, and other compliant liquid fuels.

Material Composition:​ Valve body and internal components are manufactured from corrosion-resistant materials; sealing system uses fluorocarbon rubber suitable for various liquid fuels and temperature environments.

Working Principle:​ The rotary plate valve, driven by an integrated electric actuator, modulates the metering port area. A throttling differential pressure regulator maintains a stable pressure differential across the metering port, ensuring accurate flow control. A positive displacement high-pressure fuel pump must be installed upstream of the LQ25 valve.

Performance Parameters:​ Flow metering accuracy is ±5% of actual flow or ±0.5% of maximum flow (whichever is greater). Full stroke actuation time is less than 100 milliseconds, meeting the rapid load change demands of gas turbines.

Installation Requirements:​ Install with proper ventilation and thermal management space. Ensure upstream fuel filtration meets 20 micron cleanliness. Maintain fuel water content at or below 0.1% by volume.

Usage Notes:​ Fuel must be filtered to limit particulate size to 20 microns or smaller. Verify compatibility of fluorocarbon seals with the specific fuel chemistry. Do not operate outside the specified pressure and temperature limits.
