Actuator systems (100) and methods of operation are disclosed. The systems include a hydraulic actuator (102) having a primary piston (104) having a piston head (112) arranged within a housing (106) defining retract and extend chambers (108, 110) on opposite sides of the piston head. A control element (118) is configured to control a supply of pressure to each of the retract and extend chambers. An actuator valve (124) is coupled to the housing and includes a secondary piston (126) that is biased into the retract chamber in an open flow state and when the primary piston is in a fully retracted state the piston head urges the secondary piston into a closed flow state. The actuator valve defines a flow chamber (132) where, in an open flow state, fluid can be passed through the flow chamber and in a closed flow state the fluid is prevented from passing through the flow chamber.
