Abstract: A valve positioner for controlling a valve closure element is provided. The positioner includes a positioner housing with a plurality of fluid flow passageways in fluid communication with a fluid supply source and the valve closure element. The positioner housing is configured to receive a detachable spool manifold assembly. The spool manifold assembly is positioned adjacent the plurality of fluid flow passageways. The spool manifold assembly includes a reciprocally moveable spool configured to selectively port fluid flow from the plurality of fluid flow passageways. The spool manifold assembly includes a diaphragm connected to the spool via a flexible shaft. The diaphragm is in fluid communication with a transducer for receiving a fluid causing the diaphragm to expand or contract and thereby displacing the spool. The flexible shaft is radially elastic in order to minimize axial backlash between the diaphragm and the spool. The flexible shaft configuration minimizes the spool stroke.

Abstract: A stepper actuator including a brake drum and a central gear mechanically connected thereto. The brake drum and the central gear are selectively rotatable in opposing first and second rotational directions. First and second actuation members are moveable through first and second actuation cycles to incrementally rotate the central gear. The actuation members engage and subsequently disengage the central gear as they move through their actuation cycles. The actuation members are configured to rotate the central gear during engagement therewith. A braking assembly is operatively connected to the first and second actuation members and is frictionally engaged to the brake drum to prevent rotation of the brake drum when the first and second actuation members are each in a retracted position as occurs when neither is moving through a corresponding actuation cycle. The braking assembly disengages the brake drum when one of the actuation members is moved from its retracted position and into its actuation cycle as facilitates the incremental rotation of the central gear.

Abstract: Disclosed is an actuator system for positioning a piston within a cylinder and comprising a compressed air source, a positioner, and first and second pneumatic valving modules. The first and second pneumatic valving modules respectively comprise first and second volume boosters to amplify the flow of compressed air, first and second derivative boosters to alternately supply and exhaust compressed air into and out of the first and second ends at high flow rates, and first and second commutators to selectively allow the compressed air to flow respectively between the volume boosters and the derivative boosters. A safety valve opens at a predetermined pressurization level such that the first and second commutators may be energized. A volume tank provides compressed air to each one of the first and second pneumatic valving modules upon energization of the first and second commutators.

Abstract: A fail-freeze valve positioner system is disclosed. The system has a transducer with a first type output port connectible to a valve actuator, and a second type input port receptive to a valve position signal that is proportional to an output of the first type output port. In addition, the system has a monitoring circuit that generates a pilot activation signal while predefined conditions are met. A primary piloted valve in communication with the monitoring circuit is coupled to the first valve. The first type output port is disconnected from the valve actuator while the pilot activation signal and thus the first valve are deactivated, holding the valve actuator in place.

Abstract: A method and device for controlling a process variable based upon a set point is disclosed. A process variable is measured, and a proportional term is assigned to a manipulated variable that is based upon a product of a proportional gain coefficient and an error magnitude between the process variable and the set point. An integral term is added to the manipulated variable under a first set of conditions, and a derivative term is added to the manipulated variable under a second set of conditions different from the first set of conditions. The sum of the proportional term, the integral term, and the derivative term is output, resulting in the process variable being responsively adjusted thereto.
