Product Description

The 9910021-1 is a spring-loaded relief valve that protects pneumatic and hydraulic systems from overpressure conditions. When system pressure exceeds the valve's set point, internal springs open the relief port to vent excess pressure and maintain safe operating limits. Commonly installed in environmental control system pneumatic lines on aircraft to prevent component damage and system failure.

Steel or aluminum construction with precision-machined internals. Installation and pressure adjustment must follow the aircraft maintenance manual and component 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.
