Valve Linkage, use w/M150
Y20EBD Valve Linkage for M150 Motor Actuators
The Y20EBD Valve Linkage converts the rotary motion of an M100 Series Motor Actuator to a linear movement in order to operate several types of valves. A rack and pinion drive mechanism provides the linear movement. The rack assembly contains a spring that, when compressed by over travel, will maintain valve close off to rated values. The pinion gear may be reversed for manual operation with a 3/8 inch socket drive extension for service of controlled equipment.
Note: The Y20EBD linkage kit can be used on Barber-Colman 1-1/2 to 2 inch valves. Use the grooved adapter bushing provided with the linkage kit for V-90 Series and the mid-bracket position. Larger Barber-Colman valves can mount onto the Y20EBD yoke directly; however, adding locally purchased large washers under the linkage bracket to prevent paint damage is recommended. A selection of models are available to adapt M100 Motor Actuators to several types of valves. A Y20EBD-4 linkage is available to enable an M150 Motor Actuator to operate S91 auxiliary switches for automatic heating/cooling changeover applications. The Y20EBD-4 allows additional over travel after valve close off for switch operation.
