Description

SM series has two actuators, hydraulic (SM/H) or pneumatic (SM/P), driving the stepper motor internal mechanism (clockwise and anticlockwise rotation), thus allowing the linear movement of the valve threaded stem in closing or opening direction. This actuator is tipically mounted on choke valves. Plus •Available in different sizes to meet different torque requirements •Available with two 3-way solenoid valve and other accessories •Direct connection between position transmitter and valve stem without intermediate mechanism •Linear and visible stroke indicator •Manual override detachable/attachable (user defined) •Manual override provided in case of loss of mechanism forces
*Prices are pre-tax. They exclude delivery charges and customs duties and do not include additional charges for installation or activation options. Prices are indicative only and may vary by country, with changes to the cost of raw materials and exchange rates.
