Group 11 Quarter-Turn Rotary Actuators

Beck Group 11 drives with fulcrum lever mountings provide accurate modulating control of large linear globe valves. These virtually maintenance-free assemblies reliably eliminate stick/slip and performance inconsistencies typical of pneumatic actuators.

The fulcrum lever assembly accommodates high thrusts while maintaining long-term reliability and precision. In addition, Group 11 control drives are available with hazardous location ratings.

As with any Beck Group 11 application, a wide variety of control options and features is available in this design.

Beck’s unique Tight-Seater™ coupling provides positive seating of the valve plug for tight shut-off.
