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: Disclosed is a piston positioning system for positioning a piston within a cylinder of a pneumatic circuit. The system comprises a piston position indicator for sensing an actual piston position, a controller for generating an output signal in response to the piston position signal, a pneumatic valving device for regulating the flow of pneumatic fluid and a solenoid valve configured to energize the pneumatic valving device. The pneumatic valving device comprises a four-way valve, a servo valve coupled to a stepper motor, and a two-way valve. The reversible stepper motor is incrementally rotatable over a desired angle of rotation in proportion to the magnitude of the output signal for linearly translating the servo valve such that the flow of pneumatic fluid maybe manipulated into and out of first and second ends of the cylinder to control the piston position therewithin.

Abstract: A booster valve comprising a housing having a signal port, an actuator port, a supply port, and an exhaust port disposed therein. Disposed within the housing are upper and lower plugs. The upper and lower plugs and the housing collectively define a signal chamber which fluidly communicates with the signal port, an actuator chamber which fluidly communicates with the actuator port, and a supply chamber which fluidly communicates with the supply port. The upper and lower plugs are selectively moveable between neutral, delivery and discharge positions. When in the neutral position, the actuator chamber is fluidly isolated from both the supply chamber and the exhaust port. When in the delivery position, the actuator chamber fluidly communicates with the supply chamber but is fluidly isolated from the exhaust port. Finally, when in the discharge position, the actuator chamber fluidly communicates with the exhaust port but is fluidly isolated from the supply chamber.

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.

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.

The cam plate has a groove which extends diagonally across the width thereof. The lower link is pivotably mounted to the housing and has a cam pin and a slot formed at a free end thereof. The cam pin is engageable to the groove of the cam plate. The upper link is also pivotably mounted to the housing in offset relationship to the lower link. A free end of the upper link has a link pin which is engageable to the slot. The motion converter is configured such that the lower link pivots in response to slidable movement of a cam pin within the groove during reciprocation of the cam plate. The upper link is configured to pivot in response to the slidable movement of the link pin within the slot during pivoting in a lower link.
