MEC Actuator / Fisher 1-1/4 in. Internal Valve

Designed with a heavy-duty stainless steel frame to withstand the toughest conditions. These actuators are intended to be used at remote locations or operated directly off the air brake system in bobtail or transport applications. The actuators smooth acting cam opens the internal valve lever when air, nitrogen, or carbon dioxide is applied to the line. When pressure to the line is released, the internal valve automatically closes. In case of a fire the factory provided thermal plug melts at 212F releasing pressure allowing the internal valve to close. These actuators require no modification and all hardware needed for installation is provided.|Actuator type: Airstroke by firestone|Fits the following MEC internal valve models: ME990-10, ME991-10, ME992-10, ME992-12|Field repairable without complete disconnect from internal valve|Stainless steel all weather bracket
