Application Scenarios:​ Suitable for various liquid fuel industrial gas turbines, including power generation, mechanical drive, and marine propulsion systems. Compatible with diesel, kerosene, gasoline, naphtha, gas turbine fuel oil, fuel oil, and compliant biodiesel.

Performance Parameters:​ Metering accuracy is ±5% of actual flow or ±0.5% of maximum rated flow. Valve stroke time from full open to full close is less than 100 ms, and shut-off response time is less than 100 ms.

Material Composition:​ Valve body is available in aluminum alloy or stainless steel; internal wetted parts use corrosion-resistant materials; sealing components use fluorocarbon rubber (FKM), suitable for various liquid fuel environments.

Structural Features:​ The valve adopts a rotary sleeve metering structure, with the metering sleeve driven by an external actuator through a lever mechanism. The valve body integrates a bypass valve and differential pressure regulator. Fuel connections use MS33786-20 standard interfaces, with optional overboard drain interface.

Working Principle:​ Fuel enters the valve body from the inlet, is precisely regulated by the metering port, and delivered to the gas turbine combustion chamber; the excess returns to the tank through the bypass valve. The built-in differential pressure regulator automatically adjusts the bypass valve opening through a bellows and spring mechanism, maintaining a constant differential pressure across the metering port at the set value. When the actuator adjusts the metering sleeve angle, the effective flow area of the metering port changes, achieving precise flow control under constant differential pressure.
