Actuator-Rotary For C421 And C427

PowerTorq rotary drive actuators are designed to maximize the life of the internal valve by eliminating side pressure on the valve packing stem. They are intended to be used at remote locations or operated directly off the air brake system in bobtail or transport applications. The low temperature factory-installed seals allow the actuators to be used with air, nitrogen, carbon dioxide or LP gas vapor. In case of fire, the factory-provided thermal plug melts at 212 F, releasing pressure to allow the internal value to close. The factory set rotation or these actuators requires no modification, can be oriented in any direction and all hardware needed for installation is provided.
