    Abstract: Universal control circuitry for an electro-hydraulic valve actuator system includes logic gate circuitry to control one or more of a closing solenoid valve, an opening solenoid valve, an emergency shutdown solenoid valve, and a hydraulic fluid pump motor to route hydraulic fluid through a hydraulic circuit to actuate a valve via a hydraulic actuator according to received commands. The universal control circuitry is configured to control operation for multiple different configurations of a hydraulic valve actuator system including double-acting configurations, single-acting spring-to-open configurations, and single-acting spring-to-close configurations, each with or without an emergency shutdown arrangement (which may be configured to trip based on an external shutdown input alone or in combination with a local system power failure), a hydraulic accumulator, and maintained or momentary input commands.

    Abstract: Manual hydraulic override pumps for use with actuators are described herein. An example apparatus includes a manifold including a reservoir port to be fluidly coupled to a reservoir of fluid, a pump port to be fluidly coupled to a pump, a first actuator port to be fluidly coupled to a first chamber of an actuator, and a second actuator port to be fluidly coupled to a second chamber of the actuator. The example apparatus also includes a rotor disposed in a cavity formed in the manifold. The rotor is rotatable between a first actuating position in which the rotor fluidly couples the first actuator port and the pump port, and a second actuating position in which the rotor fluidly couples the second actuator port and the pump port.

    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.
