Actuator with end stop valve

An actuator system comprising:

• a hydraulic actuator having a primary piston having a piston head arranged within a housing, the primary piston actuatable between a fully retracted position and a fully extended position, the hydraulic actuator defining an adjustable retract chamber on a first side of the piston head and an adjustable extend chamber on a second side of the piston head opposite the first side;
• a control element configured to control a supply of pressure to each of the retract chamber and the extend chamber;
• and
• an actuator valve coupled to the housing of the hydraulic actuator, the actuator valve having a secondary piston that is biased into the retract chamber in an open flow state and when the primary piston is in the fully retracted state position the piston head urges the secondary piston into a closed flow state,
• wherein the actuator valve defines a flow chamber therein, wherein in the open flow state fluid can be passed through the flow chamber and in the closed flow state the fluid is prevented from passing through the flow chamber,
• wherein the fluid that passes through the actuator valve is fluidly separate from a fluid within the hydraulic actuator.
