Actuator Mounting Components for Assembly with a Valve W8484‐1 WARNING When moving the actuator stem with diaphragm loading pressure use caution to keep hands and tools out of the actuator stem travel path. Personal injury and/or property damage is possible if something is caught between the actuator stem and other parts of the valve assembly.
  • Page 7 Instruction Manual 3024C Actuator D103048X012 June 2023 NOTICE Be sure that the length of the actuator stem and the valve stem in the connector (key 50) is equal to or greater than the diameter of that stem. Incomplete engagement of either the valve or actuator stem in the stem connector can result in stripped threads or improper operation.
