Actuation Fundamentals:

• Types:

  • Manual

  • Air Operated

  • Electric Operated

    • Interpreting Wiring Diagrams

• Actuator Sizing

  • Determining Factors

  • How to use Torque Charts

  • Direct Mount vs Brackets and Couplings

Topworks: Why do we need them and what do they do?

• Limit Switches

• Speed Controls

• Proximity Switches

• Mufflers

• Solenoid Valves

• Positioners (3-15 PP and 4-20Ma)

Troubleshooting & Assembly Workshop

• Assemble and Cycle actuated valves.

• Convert from Spring Return to Double Acting and from Fail Open to Fail Closed.

• Troubleshoot malfunctioning units to determine what is wrong with them.

  • Determine Plant Air and Electric Requirements.

  • Troubleshoot Switch positions not matching ball or disc position.

  • Troubleshoot solenoid valve installations.

  • Change orientation of Pistons to reverse actuator rotation.

  • Troubleshoot Positioner setting for both 4-20 ma and 3-15 psi.

  • Properly set Limit Switches.
