Abstract: The present invention allows for a combination valve in a hydronic HVAC system that functions as an isolation valve; a check valve; and as a device for measuring fluid parameters, such as flow rate, pressure, and/or temperature, and also allows for the isolation valve to be configured in the field to be mounted either in a straight 180° or an angled 90° orientation, as well as at an intermediate angle. The new combination of isolation valve, check valve, with embedded sensors for flow rate, pressure, and/or temperature measurement provides a more compact product envelope that achieves space savings, e.g., by eliminating the need for separate components in an HVAC system, such as separate isolation valves, check valves, flow meters, pressure gages, and/or thermometers.

Abstract: The present invention provides for a device or feature that incorporates a technique or means for flow measurement in a fluid flow system. By way of example, a contoured insert may be specifically calibrated to the pipe line size to ensure the desired accuracy of the flow measurement, irrespective of pipe length between the device and other fluid system components that would negatively influence other flow rate measurement devices. This in turn reduces the total number of components needed in a system.

Abstract: A contoured check valve disc features a pivot portion and a check valve portion. The check valve portion is attached to the pivot portion, and has two sides, a first side to respond to the fluid flow in a first direction and move the check valve portion away from a fluid opening to the one or more open positions depending on the fluid flow to allow the fluid to flow through the fluid opening, and a second and opposing side to respond to fluid flow in an opposite direction through the fluid opening and move the check valve portion towards the fluid opening to the closed position to seal the fluid opening and stop fluid flow. The check valve portion a near-sloped portion formed nearest to the pivot portion, having a near-sloped contoured surface curving away from the pivot point to a first point of inflection with a first curvature, and a far-sloped portion formed farthest from the pivot portion, having a far-sloped contoured surface curving away from the point of inflection towards a farthest point away from the pivot portion with a second curvature that is less curved or bent than the first curvature, the near-sloped portion and the far-sloped portion combining to form a combined surface having a contoured pressure/force distribution on the first side to respond to the fluid flow and move the check valve portion away from the fluid opening.

Abstract: A valve is provided having a valve housing/body configured to be arranged in, or form part of, a piping having a fluid flow, and configured with a pressure tap arranged at a location along the piping to allow pressure of the fluid flow of the piping to be measured, and also having a rotatable orifice plate configured to rotate in the valve body/housing on an axis of rotation positioned at a different location along the piping than the pressure tap for rotating between a first rotatable position for providing a normal fluid flow operation and a second rotatable position substantially perpendicular to the fluid flow for providing a direct flow measurement of the fluid flow determined based on signaling sensed by the pressure tap sensor containing information about a measured pressure at the pressure tap when the orifice plate is in the second rotatable position.
