Frequently Asked Questions (FAQ)
Q: Are YM aviation valves direct replacements for OEM parts like Parker, Eaton, or Woodward?
A: Many of our products, including the Aviation Valve T-5T, are designed as form-fit-function equivalents. We provide detailed comparison datasheets and interface drawings to facilitate your engineering evaluation and qualification process. We position ourselves as a reliable alternative or secondary source.
Q: What is your lead time for standard and custom components?
A: Lead times vary by product complexity and order volume. Standard catalog items like the Cold Air Solenoid Valve QDF-42A typically have shorter lead times (e.g., 4-8 weeks). Customized or large-volume orders are planned collaboratively. We provide firm lead times with each quotation.
Q: Do you provide components for both commercial and military aircraft programs?
A: Yes. Our military-grade valves and components are suitable for defense applications requiring ruggedness. Simultaneously, our production under AS9100 and design adherence to relevant SAE standards make our products applicable for commercial aviation MRO and OEM support.
Q: How do I select between a solenoid valve (QDF-42A) and a manual valve (YSF-1A) for a cooling application?
A: The choice depends on system control logic. Solenoid valves allow for automated, remote control via the aircraft's computer and are ideal for frequent or scheduled operation. Manual valves are used for service isolation, backup, or in systems rarely adjusted. Our engineers can advise based on your specific functional and safety requirements.
Q: What support do you offer for integrating your temperature sensors or pressure transducer hydraulic units?
A: We provide comprehensive technical documentation: wiring diagrams, calibration curves, installation torque specs, and material compatibility guides. For complex integrations, our engineering team is available for technical consultation to ensure optimal performance within your system, which may also include other security sensors in the aviation environment.
