Marshall Excelsior ME206 Air Actuator for 2" & 3" Internal Valves

The Marshall Excelsior #9 Chamber Power Stroke Air Actuator (ME206) is engineered for robust performance in demanding environments. This actuator is designed to be used at remote locations or directly off the air brake system in bobtail or transport applications. It features a heavy-duty stainless steel frame and a smooth-acting cam that opens the internal valve lever when air, nitrogen, or carbon dioxide is applied. The actuator automatically closes the internal valve when the pressure is released. In case of a fire, the factory-provided thermal plug melts at 212°F (100°C), releasing pressure to close the internal valve. No modifications are needed for installation, and all necessary hardware is included.

Key Features:

• Heavy-Duty Construction: Stainless steel frame for durability in tough conditions.
• Smooth Operation: Cam mechanism ensures smooth opening and closing of the internal valve.
• Automatic Safety: Thermal plug melts at 212°F (100°C) to close the valve in case of fire.
• Easy Installation: No modifications required; all hardware included.
• Compatible Valves: Fits MEC models ME990-16, ME990-24, ME990S-3F-24, ME990S-2DFM, ME991-16, ME991-24, ME992-16, ME992-24, ME993S-16, ME993S-24, ME994S and Fisher® models C402, C421, C471, C427, C477.
