In an open position of the spool valve, a first control fluid inlet is fluidly connected to a first control fluid outlet, and in a closed position of the spool valve the first control fluid outlet is fluidly connected to a second control fluid outlet. A method of determining an optimum stroke speed includes iteratively powering a main and secondary solenoid in the electrical module and updating parameters to move a control element of the control valve until movement of the control element is within a desired range.

    Abstract: A liquid dispensing valve (12) including a liquid inlet (90) for receiving the liquid and a liquid outlet (92) for discharging the liquid. A valve member (44) is mounted for movement relative to the liquid outlet (92) between open and closed positions. A liquid passage (96) communicates between the liquid inlet (90) and the liquid outlet (92). An air inlet (114) is provided for receiving air from a source of pressurized air. An air passageway (120 and/or 128) is coupled with the air inlet (114). A pneumatic actuator (40, 110, 112) communicates with the air passageway (120 and/or 128) for moving the valve member (44) at least to the open position. An electrically operated air supply device (70) interacts with the air passageway (120 and/or 128) so as to control the flow of pressurized air to the pneumatic actuator (40, 110, 112).

  • Patent number: 8783027
    Abstract: A pressure regulation circuit delivers pressurized fluid into a generator. The circuit includes pressure regulator structure and a primary valve. The pressure regulator structure outputs pressurized fluid at a predetermined output pressure that is greater than a desired operating pressure of the generator and less than a predetermined upper alarm pressure. The primary valve is downstream from the pressure regulator structure and is selectively opened and closed by a controller based on the pressure within the generator. The controller opens the primary valve to allow the pressurized fluid outputted from the pressure regulator structure to flow into the generator upon the pressure within the generator being at or below a predetermined lower limit. The controller closes the primary valve to prevent the pressurized fluid outputted from the pressure regulator structure from flowing into the generator upon the pressure within the generator being at or above a predetermined upper limit.

    Abstract: A proportional motion control valve includes an electro-mechanical actuator that provides an infinitely controlled pressure setting in response to an electric signal applied to the electro-mechanical actuator. In another aspect, a proportional motion control valve includes a pilot-operated valve disposed intermediately with respect to a cage and a valve body to fluidly isolate an internal cavity of the valve body from a bore of the cage. The pilot-operated valve is subjected to a hydraulic opening force of pilot fluid that is present in the bore of the cage. A spring is disposed within the internal cavity of the valve body and arranged to subject the pilot-operated valve to a closing spring force.

  • Patent number: 8746275
    Abstract: A stepper-motor gas valve control is disclosed that includes a main diaphragm in a chamber that controllably displaces a valve relative to an opening in response to changes in pressure, to adjust fuel flow through the valve. A servo-regulator diaphragm is provided to regulate flow to the main diaphragm, to thereby control the rate of fuel flow. A stepper motor is configured to move in a stepwise manner to displace the servo-regulator diaphragm, to control fluid flow to the main diaphragm. A controller mounted on the stepper-motor regulated gas valve control receives and converts an input control signal from a heating system to a reference value between 0 and 5 volts, and selects a corresponding motor step value. The control responsively moves the stepper-motor in a step wise manner to displace the servo-regulator diaphragm and thereby regulates the rate of fuel flow through the valve.
