摘要： A gas-over-oil actuator system for use with a valve in a natural gas pipeline. The system includes a gas-over-oil actuator and a wireless position monitor operatively coupled to the gas-over-oil actuator. The wireless position monitor includes an integral opened spool valve and is adapted to be communicatively coupled to a remote workstation via a wireless network and a wireless gateway. At least one switching relay is operatively coupled to the gas-over-oil actuator and the wireless position monitor. Upon receiving a wireless command from the remote workstation, the wireless position monitor drives a pressure signal from the opened center spool valve to the at least one switching relay to manage high pressure supply to the gas-over-oil actuator and move the valve to a desired position.

摘要： Servo gas system (11) realised as a modified hydraulic Wheatstone bridge for a gas burner (10), namely for controlling a pressure regulation valve (20) positioned in a gas duct (18) of the gas burner, thereby controlling a pressure difference between a pressure (P1) in a burner chamber (12) of the gas burner and the gas pressure (P6) within the gas duct (18). The hydraulic Wheatstone bridge embodiment comprises a static servo gas flow branch (28) and a dynamic servo gas flow branch (29) being connected in parallel, a flow sensing element (30) being connected between the static servo gas flow branch (28) and the dynamic servo gas flow branch (29) and providing a signal used to control the pressure regulation valve (20) by an electric actuator (41). The static servo gas flow branch (29) comprises a first (32) and a second flow restricting device (33) in serial connection. The dynamic gas flow branch (29) comprises a pressure regulator (37) and downstream of the pressure regulator (37) a third flow restricting device (38) in serial connection. The flow sensing element (30) is connected to the connection between the two flow restricting devices (32, 33) of the static servo gas flow branch (28) and to the connection between the pressure regulator (37) and the third flow restricting device (38) of the dynamic servo gas flow branch (29). The pressure regulator (37) is further connected to a reference pressure, preferably the combustion chamber pressure (P1).

摘要： This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one illustrative but non-limiting example, a valve assembly may include a valve body, a valve situated in a fluid path of the valve body, a valve actuator for selectively moving the valve actuator, one or more sensors in communication with the fluid path, a controller secured relative to the valve body and in communication with the sensors, and memory operatively coupled to the controller. A user interface may be in communication with the memory and the controller and may be configured to receive a selection from a user for selecting one of two or more selectable options from the memory. The controller may compare sensed parameters to threshold values associated with the selected option. The user interface may have a lock on it to prevent tampering and to provide accountability.

摘要： A digitally controlled current to pressure converter (CPC) (102) is provided. The digital CPC (102) utilizes a digital controller (124) and an onboard pressure transducer (158) to accurately control the output pressure based upon an input analog control signal. The digital controller (124) includes an anti-silting algorithm that provides an impulse movement to a three-way rotary valve (140) of the CPC (102) to loosen and flush away silt contamination from the valve (140). A redundant seal stack including an intermediate passage (154) to the hydraulic drain ensures a low pressure drop across the outboard seal (156) minimizing the potential for leakage and improving reliability of the CPC (102). The digital controller (124) also includes redundancy and fault management algorithms that enable the use of multiple inputs and feedback signals for control of the CPC (102). Master/slave operation and transitioning is also provided by the digital controller (124).

摘要： A 'plug and play' process control valve 10 providing closed loop feedback control has a built in microprocessor 40, stepper-motor 20, a position encoder, a valve body having an inlet 11 and an outlet 12, and pressure sensors 30, 31 positioned within the inlet 11 and the outlet 12 of the valve body, the pressure sensors being connected to the microprocessor 20, which is in turn connected to an input from the position encoder, and provided with outputs to the stepper-motor 40. Within the valve body there are a pair of apertured ceramic shear action discs 13, 14. The stepper-motor rotates the upper disc 14 relative to the apertured stator disc 13 to control pressure or flow in the pipeline.

摘要： A closed loop pressure controller system that sets, measures and controls the process pressure within a semiconductor process is shown. The system is commonly composed of a pressure sensor (22) to collect the pressure information, a controller box that hosts the control electronics, and a valve (28) to physically affect the conductivity of the inlet or outlet gas line (26) and accordingly the process pressure. The present invention differs from the prior art by using closed-loop motor control of the valve, rather than the method of the prior art, where the valve position is controlled by a stepper motor actuator driven in an open loop fashion. It is demonstrated that the utility of such prior art open-loop configurations is limited by the fact that the achievable precision of the valve position is hindered by static friction in the valve system, and the non-linear character of the torque versus shaft-angle of the motor (among other error components). The method of the present invention more accurately positions the valve, and accordingly enhances the overall precision and allowable loop-gain of the pressure control system by providing the valve drive with feedback as to the actual angular position of the valve in extremely high resolution.

摘要： Ein Druckgeber für die Erzeugung eines geregelten Unter- oder Überdrucks umfasst ein mit Druckluft beaufschlagbares Ventil (1), einen Motor (10) zum Verstellen der Lage des Ventilkopfes (14), einen Sensor (8) zur Messung des zu regelnden Druckes und einen elektronischen Regler (9). Das Ventil besteht aus einem mit einem Ventilsitz (13) zusammenwirkenden Ventilkopf. Die Drehbewegung der Welle (11) des Motors (10) wird mittels einer Kupplung (12) in eine Längsbewegung des Ventilkopfes umgesetzt. Zwischen der Welle (11) des Motors (10) und dem Ventilkopf ist eine Feder (20) eingesetzt, die den Motor (10) mechanisch so belastet, dass der Motor (10) die vom Regler (9) vorgegebene Soll-Drehzahl nicht erreicht, sondern langsamer dreht. Die Belastung des Motors (10) ist abhängig von der Stellung des Ventilkopfes. Dies ist für den Regler gleichbedeutend mit einer Linearisierung der Kennlinie der Regelstrecke.
