These actuators are intended to be used at remote locations or operated directly off the air brake system in bobtail or transport applications. The actuator’s 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.

These actuators are designed to maximize the life of the internal valve by eliminating side pressure on the valve’s packing stem. The low-temp factory seals allow these actuators to be used with air, nitrogen, carbon dioxide, or LP-Gas vapor.
