Product Description
The 21700-1001 is a thermal relief valve (7SC0127) for aircraft hydraulic systems. This valve automatically vents excess pressure caused by fluid thermal expansion in closed hydraulic lines, preventing overpressure conditions during temperature changes. Commonly installed in sealed sections of hydraulic circuits on business and transport aircraft.
The valve opens at a preset pressure threshold to release small fluid volumes, then reseals as pressure normalizes. Installation and testing must follow the applicable aircraft maintenance manual and component specifications.
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.
