Product Description
The 9870038/B is a relief valve designed to protect hydraulic and pneumatic aircraft systems from overpressure conditions. When system pressure exceeds the set threshold—caused by regulator faults or thermal expansion—the valve vents excess fluid or gas and then reseats automatically. This prevents downstream component damage and system failure.
The valve conforms to applicable MS and NAS aerospace standards for reliability and performance. Installation and pressure adjustment must follow the aircraft maintenance manual and component manufacturer specifications to ensure proper system protection.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
