Page 18: Setting Travel Limit Valves
Installation, Operation and Maintenance Manual Section 9: Setting Travel Limit Valves Part Number: E7K-400-0413 April 2013 Section 9: Setting Travel Limit Valves Before setting limits it must be noted that actuators ordered specifically for torque-seated valve applications are assembled at the factory without tubing on the closing side limit valve. The close side limit valve is physically installed but the tubing bypasses it and runs directly to the torque limit. - Page 19 Section 9: Setting Travel Limit Valves Installation, Operation and Maintenance Manual April 2013 Part Number: E7K-400-0913 Determine full-close valve position Close the valve completely using the handwheel. Observe rotational direction of adjusting shaft (3) during closing. Once the valve is closed, open it several turns (counterclockwise) to prevent overtravel.
