LB (Linear Base) Advantages
Advantages of the LB include an easily assembled
mechanical base that converts actuator torque to linear
thrust. The standard A1 base is used to accept the valve
thrust component, and both the LB and A1 base are available
in either MSS or ISO flanges. This means that either an MX
or QXM actuator that has an A1 thrust base can be readily
fitted for its corresponding LB1 or LB2 base. Both the LB1
and LB2 can be ordered with the “EN” base as optional.
This permits stem protection and satisfaction of EN 15714,
Electric Actuators for Industrial Valves Requirements. The
bases are also compliant with ATEX 94/9/EC certification.
