Abstract: Control fluid power apparatus and related methods are disclosed. An example control fluid power apparatus includes a first housing having a first piston defining a first chamber and a second chamber, where the first chamber receives a control fluid and the second chamber receives a process fluid from a process system. The first chamber is oriented above the second chamber when the control fluid power apparatus is coupled to a control valve assembly. A second housing has a second piston defining a third chamber and a fourth chamber, where the third chamber receives the control fluid and the second chamber receives the process fluid. The third chamber is oriented above the fourth chamber when the control fluid power apparatus is coupled to the control valve assembly.

Abstract: The present disclosure envisages a system and method for self-calibration of an actuator. The system comprises a pressure spike sensing and control circuit, a travel limit setting circuit and a profile generation circuit. The pressure spike sensing and control circuit is configured to check and set an operating pressure of the actuator. The travel limit setting circuit is configured to check and set the travel limit of the actuator. The profile generation circuit is configured to generate the profiles of a set of parameters of the actuator.

Abstract: Methods and apparatus to charge accumulators are described An example system to charge an accumulator apparatus (100) includes a piston (104) disposed within a housing (102) to define a first chamber adjacent a first side (106) of the piston and a second chamber adjacent a second side (108) of the piston. A fill probe (202) having a body and a passageway between a first end (306) of the fill probe and a second end (308) of the fill probe removably couples to the piston to fluidly couple to the passageway of the fill probe to the second chamber of the housing when the accumulator is in a charging condition. A valve (142) is fluidly coupled to the piston to enable fluid flow to the second chamber of the housing via the piston (104) when the fill probe is coupled to the piston (104).
