Review GRUMMAN Aircraft Selector Valve P/n
Introducing the Grumman 90555-1 Aircraft Selector Valve, a critical component for aviation systems that ensures the proper distribution of hydraulic fluid to various flight control surfaces. This selector valve is an essential part of the Grumman Avionics System, widely used in various aircraft models, including the Grumman E-2 Hawkeye and C-2 Greyhound.
The Grumman 90555-1 Aircraft Selector Valve is a pneumatically operated, three-position, 2-way valve. It features a robust design with a 3/4 inch NPT threaded inlet and outlets, enabling easy installation and maintenance. This valve is constructed primarily from durable materials, such as high-strength aluminum alloy and brass, ensuring long-lasting performance even in extreme operating conditions.
The selector valve operates by receiving pneumatic signals that activate the valve to select between two hydraulic systems. The valve has three positions: 'Normal,' 'Alternate,' and 'Off.' In the 'Normal' position, hydraulic fluid is supplied to the primary system. In the 'Alternate' position, hydraulic fluid is supplied to the secondary system. The 'Off' position shuts off the flow of hydraulic fluid to both systems.
The Grumman 90555-1 Aircraft Selector Valve is designed to meet the stringent requirements of the aviation industry, including FAR 25 and FAR 27 regulations. It undergoes rigorous testing to ensure its reliability and functionality under various conditions, such as temperature extremes and vibration.
This selector valve comes complete with necessary mounting hardware and gaskets. It is important to note that it is recommended to replace the O-rings whenever the valve is serviced or overhauled to ensure a tight seal and prevent potential leaks.
In summary, the Grumman 90555-1 Aircraft Selector Valve is an essential component of avionics systems, ensuring the proper distribution of hydraulic fluid to various flight control surfaces. Its robust design, durability, and reliable performance make it an ideal choice for aviation applications.
The Grumman 90555-1 aircraft selector valve is a crucial component in aviation systems that controls the flow of hydraulic fluid between the primary and secondary flight control systems. When considering purchasing this part, it is essential to weigh its pros and cons to ensure it is the right decision for your specific situation.
