Valve with combined rotation stop and stem blowout prevention

A method of assembling a valve, the method comprising:

• arranging a valve stem to an assembly position relative to an actuator flange;
• arranging an end stop plate such that one or more cutouts in the end stop plate are aligned with respective tabs of the actuator flange;
• aligning the end stop plate with an engagement portion of the valve stem and translating the end stop plate along a rotation axis of the valve into a recess of the actuator flange such that one or more end stop plate translation portions of the end stop plate translate past the tabs;
• and
• rotating the end stop plate and valve stem such that the end stop plate translation portions are disposed underneath the tabs.

A valve comprising:

• an actuator flange forming a recess;
• a valve stem disposed through the recess of the actuator flange;
• and
• an end stop plate:
• disposed within the recess of the actuator flange;
• coupled to the valve stem such that rotations of the valve stem and the end stop plate around a rotation axis of the valve are coupled;
• and
• configured to interface with fasteners disposed within the recess such that:
• the end stop plate is prevented from translating out of the recess;
• the end stop plate can rotate around the rotation axis;
• and
• a rotation of the end stop plate around the rotation axis is limited in at least one direction.
