Rotary Actuators

MNxx20 175 lb-in. and MNxx34 300 lb-in. Non-Spring Return Direct Coupled Actuators

MNxx20/34 non-spring return damper actuators with 175 or 300 lb-in of torque provide modulating or floating control for rotary valves, linear valves with appropriate linkage, and air damper applications.

Overview

MNxx20 175 lb-in. and MNxx34 300 lb-in. Series Non-Spring Return Direct Coupled Actuators (DCA) are used within heating, ventilating, and air-conditioning (HVAC) systems. They can drive a variety of quarter-turn, final control elements.

Applications include: Volume control dampers, mounted directly to the drive shaft or remotely (with the use of accessory hardware). Quarter-turn rotary valves, such as ball or butterfly valves mounted directly to the drive shaft. Linear stroke globe or cage valves mounted with linkages to provide linear actuation.
