Bidirectional travel stop assembly for compact actuator

A system, comprising:

• a bidirectional travel stop assembly, comprising:
• a first travel stop configured to block a first axial movement of an actuation element of a valve actuator;
• a second travel stop configured to block a second axial movement of the actuation element;
• and
• a travel stop bushing configured to block adjustment of the second travel stop and allow adjustment of the first travel stop when the travel stop bushing is disposed within the valve actuator in a first axial orientation, wherein a first axial end of the travel stop bushing is an innermost end of the travel stop bushing within the valve actuator in the first axial orientation, wherein the travel stop bushing is configured to enable adjustment of the second travel stop when the travel stop bushing is disposed within the valve actuator in a second axial orientation, and wherein a second axial end of the travel stop bushing opposite the first axial end is the innermost end of the travel stop bushing within the valve actuator in the second axial orientation.

A system, comprising:

• a valve;
• and
• a valve actuator coupled to the valve, wherein the valve actuator comprises:
• an actuation element;
• a first travel stop, wherein a first axial position of the first travel stop is configured to limit a first axial movement of the actuation element;
• a second travel stop, wherein a second axial position of the second travel stop is configured to limit a second axial movement of the actuation element, wherein the first axial position of the first travel stop and the second axial position of the second travel stop are separately and independently adjustable;
• and
• a travel stop bushing configured to block adjustment of the second travel stop and allow adjustment of the first travel stop when the travel stop bushing is in a first axial orientation within the valve actuator, wherein the travel stop bushing is configured to enable adjustment of the second travel stop when the travel stop bushing is in a second axial orientation within the valve actuator, wherein a first axial end of travel stop bushing is disposed within the valve actuator first when the travel stop bushing is in the first axial orientation, and wherein a second axial end of the travel stop bushing opposite the first axial end is disposed within valve actuator first when the travel stop bushing is in the second axial orientation.
