Section 8: Travel and Torque Limits Installation, Operation and Maintenance Manual April 2013 Part Number: E7K-400-0913 Pneumatic valve details: • Maximum operating pressure rating - 125 psig • Flow coefficient – 0.1 (20 CFM at 125 psig) • Port size – 1/8 NPT •...
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.

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.
Installation, Operation and Maintenance Manual Section 10: Setting Torque Limit Valves Part Number: E7K-400-0413 April 2013 Section 10: Setting Torque Limit Valves Torque limit valves prevent mechanical overload in the Closed (TVC) and Open (TVO) positions. The torque limit valves are mounted in a stacked configuration. The top torque limit valve (TVO) controls the actuator opening torque and the bottom limit valve (TVC) controls the actuator closing torque.
Section 10: Setting Torque Limit Valves Installation, Operation and Maintenance Manual April 2013 Part Number: E7K-400-0913 10.2 Closing Torque Using the handwheel, close the valve completely while observing the Torque Dial rotation for a reference operating point. Figure 7 Set Closing Value Refer to the EIM Job Specification Sheet for additional suggested setpoints.
