IDEA #8AU53L Bi-directional rotary output actuator

A rotary valve is opened and closed with a combination incremental rachet mechanism and a continuous motor mechanism. Two separate control circuits are used for opening and closing the valve. When the opening or closing circuit is energized alone, the valve is incrementally opened or closed by the ratchet respectively. When the opening circuit is energized and the closing circuit is subsequently energized, the valve is continuously opened by the motor. Likewise, when the closing circuit is energized and the opening circuit is subsequently energized, the valve is continuously closed by the motor. https://app.acclaimip.com/pdf/WVBgNGFA4QD4UGBRhEDhDJNbUC8kyBTjHuta1Fg/US6302128
