🔍 Key Concepts

• Electric valve actuator control in Limitorque-style operators • Difference between a torque switch and a limit switch in stopping a motor • How non-butterfly valves (like gate/globe) reach the closed position – by torque (seating force) vs. by travel limit (position)

💭 Think About

• Look at how a non-butterfly valve actually indicates it is fully closed: is it primarily by reaching a set position or by building up mechanical seating force? • Which device in the drawing is connected to the drive so that it senses increased load or resistance on the stem as the valve seats? • Which type of switch is normally used to stop motion based on travel distance, and which is used to stop motion based on load/force on the mechanism?

✅ Before You Answer

• Identify on the illustration which component is labeled as the torque-sensing mechanism and which is the travel/position mechanism. • Confirm which type of valve (butterfly vs. non-butterfly) typically needs a seating force limit to avoid damage when it slams shut. • Verify which listed option is specifically designed to trip when mechanical load/torque reaches a setpoint, rather than when a certain angle or position is reached.
