1134218 – Textron Aviation OEM Valve
Available now on the Airparts.aero Marketplace.
Overview
The Textron Aviation 1134218 is a genuine OEM, electrically operated fuel shutoff valve, a flight-critical component engineered for the fuel systems of a wide range of Cessna single-engine aircraft. This valve is typically located on the firewall and serves as the primary means of controlling fuel flow from the tanks to the engine. It is a solenoid-actuated valve, designed to provide a positive, instantaneous fuel shutoff from the cockpit switch. Manufactured to Textron's exact specifications, this valve ensures the highest level of reliability for both normal and emergency operations.
Key Features
- Solenoid Actuation: Features a robust, high-force electrical solenoid. When actuated by the cockpit fuel shutoff switch, the solenoid drives a plunger to open or close the valve, providing rapid and reliable control over the fuel supply to the engine.
- Positive Sealing: The internal valve mechanism is designed to create a positive, leak-proof seal when in the closed position, completely isolating the engine from the fuel supply. This is a critical function for securing the aircraft and for emergency procedures such as an in-flight engine fire.
- Durable Construction: Constructed from a high-quality, corrosion-resistant metal body and features internal seals made from advanced elastomers formulated for long-term compatibility with aviation gasoline (Avgas).
- Firewall Forward Design: Specifically engineered to be mounted on the engine-side of the firewall, with materials and construction robust enough to withstand the high temperatures and vibration of the engine compartment.
- Genuine Textron OEM Part: As the genuine factory component, it guarantees a perfect fit, correct electrical characteristics, and the proven reliability required for a flight-critical fuel system component.

- Cessna 182 Skylane (later models)
- Cessna 206 Stationair
- Cessna 210 Centurion
Applications
The 1134218 is a critical component for both safety and normal aircraft operation:
- Emergency Fuel Shutoff: Its primary safety function is to allow the pilot to immediately shut off the fuel supply to the engine in the event of an engine fire.
- Normal Operations: Used to secure the aircraft after shutdown, preventing fuel from flowing into the engine fuel system when the aircraft is parked.
- Fuel System Maintenance: Allows mechanics to isolate the engine from the fuel tanks to safely perform maintenance on engine-driven fuel pumps, carburetors, or fuel control units.
- Component Replacement: The primary part used to replace a valve that is leaking, inoperative, or has failed an operational check.
Why Choose 1134218?
The ability to reliably control the flow of fuel to the engine is one of the most fundamental safety requirements of any aircraft. A leaking or inoperative fuel shutoff valve can be a catastrophic failure point. Using a genuine Textron Aviation 1134218 OEM valve is the only way to ensure the component has the correct electrical specifications, material compatibility, and positive sealing characteristics as certified by the manufacturer. For a component this vital to flight safety, there is no substitute for factory-original parts.

The 1134218 valve is a normally-closed solenoid valve. This "fail-safe" design means that it requires electrical power to open and allow fuel to flow. In the event of a total electrical failure, the valve will automatically close, shutting off fuel to the engine. While this seems counter-intuitive, it is a design choice that prioritizes preventing an electrically-fueled fire over continued engine operation in a total electrical failure scenario. The solenoid itself consists of a coil of wire that, when energized, creates a powerful electromagnetic field. This field retracts a spring-loaded ferrous plunger, which is connected to the valve gate. When power is removed, the spring forcefully returns the plunger to its original position, closing the valve and ensuring a positive fuel cutoff.
Note: This is a flight-critical fuel system component. Installation must be performed by a certified A&P mechanic in accordance with the current Textron Aviation maintenance manual. A thorough functional check and leak check of the valve and its connections must be performed after installation.
