Valve Assemblies with Mx40-704x Spring Return TAC DuraDrive Actuators
Note: The Ball Valve Assemblies use the basic Mx41-6043, Mx41-6083, and Mx40-704x TAC DuraDrive actuators.
Specifications for actuators containing auxiliary switches are also provided here. Ball valve assemblies using the
switch-equipped actuators may be field-assembled using ball valve body/linkage assemblies (VB-2x13-500-9-xx).
