Jamesbury M Series Manual Gear Actuator

Brand: Valmet

Type M Series gear actuators are recommended for use on Jamesbury ball and butterfly valves. 

For the sake of convenience, and where lever-handles presents pace problems, gear actuators are the ideal choice. 

Type M Series actuators are fully enclosed and weather-proof. They are factory lubricated for their lifetime, and each unit includes a pointer to indicative valve position. 

Standard M units are temperature rated from -40° to 80° C (-40° to 176° F). 

Type M Series actuators are available factory-mounted on valves or separately for field installation.
