Detailed content
Technical Specifications:
- Working Medium: Natural gas, treated clean gas fuel
- Gas Filtration Requirement: 25 µm absolute filtration
- Operating Pressure: Complies with industrial gas system standard specifications
- Flow Capacity: Matched to full operating conditions of small-to-medium turbine engines
- Ambient Temperature Range: -20 °C to +80 °C
Functional Features: The metering port adopts precision manufacturing technology, ensuring stable and excellent repeatability of flow characteristics. The structure is compact and robust, suitable for high-vibration and space-constrained power environments. It adopts proven sealing technology to ensure a safe and leak-free gas system.
Application Scenarios: Small-to-medium industrial gas turbine generator sets, combined heat and power and distributed energy systems, gas engine fuel management systems, marine and offshore platform gas power devices, and precise gas metering and control in industrial processes.
Material Composition:
- Valve Body: Aviation-grade aluminum alloy or precision cast stainless steel
- Metering Spool: Surface-hardened wear-resistant alloy steel, precision ground
- Sealing Elements: Gas-resistant fluororubber (FKM) composite material
- Connection Fasteners: High-strength corrosion-resistant alloy steel
Structural Features: Precision metering port with a precise functional relationship between flow and opening. Standard flange or threaded connection ports facilitate pipeline system integration. The actuator mounting interface is precisely machined to ensure coaxiality. Internal flow passages are smooth, reducing turbulence, noise, and pressure loss. The overall structure is verified for anti-vibration and anti-shock, adapting to long-term operation of power devices.
Working Principle: Gas enters the valve from the system pipeline through the inlet port and flows to the turbine combustion system after passing through the precisely metered port.
Installation Requirements: Standardized interface design facilitates integration with TM series, EM series actuators, and other control systems.
Usage Precautions: Ensure 25 µm absolute filtration of the gas supply. Operate within the specified ambient temperature range. Ensure proper sealing to prevent gas leaks.
