    摘要： The present inventive concept relates to a pilot valve. The pilot valve comprises: a pilot valve body comprising: a chamber, a first fluid inlet and a second fluid inlet for providing fluid to the chamber, and a fluid outlet for receiving fluid from the chamber. The pilot valve further comprises a separating element and a valve rod, the valve rod is arranged to control fluid flow from the first or second fluid inlet to the fluid outlet via the chamber. The separating element is connected to, and movable with the valve rod, and has a first fluid contacting area configured to be in fluid communication with the first fluid inlet, and a second fluid contacting area configured to be in fluid communication with the second fluid inlet and arranged on an opposite side to the first fluid contacting area. The pilot valve is at least partly controlled by a difference between a first force and a second forces acting on the first and second fluid contacting areas of the separating element.

    摘要： 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.

    摘要： An air flow control valve including: a valve body having an internal cavity and an inlet and outlet in flow communication with the internal cavity, the axes of the inlet and outlet being aligned at substantially 90° to each other; a valve seat located within the cavity and co-axially aligned with the outlet, the valve seat being located on the distal end of an upstanding tubular pedestal which is formed around the outlet; the internal cavity being configured so as to define an annular space around the pedestal with which the inlet is in flow communication; a flexible generally planar diaphragm mounted above the valve seat, the diaphragm supporting a valve closure member which is adapted to engage the valve seat to close the valve; valve control means for causing the diaphragm to move towards and away from the valve seat to close and open the valve respectively; and the valve being characterised in that, with the valve oriented with the inlet axis horizontal and the outlet facing downwards, the valve seat is located at an elevation at or below the upper most edge of the inlet, and the diaphragm is located at an elevation above the upper most edge of the inlet.
