Product Description for Auto Valve 2908-4AS (4820-00-115-9773) - Aircraft Bleeder Valve

The Auto Valve 2908-4AS, also known as 4820-00-115-9773 in military specifications, is a high-performance pneumatic bleed valve designed specifically for use in aircraft applications. This valve is a critical component in the aircraft hydraulic system, ensuring efficient and effective bleeding of air from the hydraulic lines during system refill.

The Auto Valve 2908-4AS is a four-port, normally closed, solenoid-operated valve. It features a compact and lightweight design, making it ideal for installation in confined spaces within aircraft. The valve body is constructed from high-strength aluminum alloy, providing excellent durability and resistance to corrosion.

The valve operates using a solenoid, which is activated when the hydraulic system pressure drops below a certain threshold. When the solenoid is activated, the valve opens, allowing hydraulic fluid to flow through and bleed air from the system. Once the air has been purged, the solenoid deactivates, and the valve closes, preventing further fluid flow.

The Auto Valve 2908-4AS is designed to meet the stringent requirements of military and aerospace applications. It is certified to MIL-SPEC 4820, which ensures that it meets the highest standards for materials, manufacturing, and performance. The valve is also compatible with a wide range of hydraulic fluids, including mineral oil, synthetic oil, and fire-resistant fluids.

In summary, the Auto Valve 2908-4AS (4820-00-115-9773) is a versatile and reliable pneumatic bleed valve that is essential for ensuring the safe and efficient operation of aircraft hydraulic systems. Its compact design, durability, and compatibility with various hydraulic fluids make it an excellent choice for military and aerospace applications.
