Abstract: A combination valve includes an isolation shutoff valve to prevent a fluid flow; a check valve to prevent backflow and gravity circulation of fluid flow; a pressure sensor to sense a pressure measurement of fluid flow and determine pressure sensor signaling containing information about a sensed pressure measurement; a temperature sensor to sense a temperature measurement of fluid flow and determine temperature sensor signaling containing information about a sensed temperature measurement; and a flow measurement sensor to sense a flow measurement of fluid flow and determine flow measurement signaling containing information about a sensed flow measurement. The pressure sensor, temperature sensor and flow measurement sensor are all embedded and preassembled in the combination valve with the isolation shutoff valve and the check valve as part of one integral composite unit or component, so as to form a combination isolation valve and check valve with integral flow rate, pressure and/or temperature measurement.

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.

Abstract: A suction diffuser or arrangement is provided featuring a main suction diffuser body and a flow conditioning arrangement. The main suction diffuser body is configured with an inlet to receive an incoming fluid flow, an interior cavity to receive the incoming fluid from the inlet, and an outlet to receive the incoming fluid from the interior cavity and provide an outgoing fluid. The flow conditioning arrangement is configured in relation to the inlet and also comprises a flow conditioning portion having at least one inwardly contoured surface, configured to extend into the interior cavity, diffuse the incoming fluid passing from the inlet into the interior cavity, and provide a flow conditioning that produces a uniform flow of the outgoing fluid by directing the incoming fluid towards the outlet, based at least partly on a contoured design corresponding to the at least one inwardly contoured surface.

Abstract: A balance or flow limiting valve features a valve body/member having a flow rate indicator/scale containing setting having printed flow rates calibrated in units of measure in volume per time increment between a minimum flow rate position (MIN) and a maximum flow rate position (MAX); and a knob/handle having a position indicator and being moveable to any continuous position on the flow rate indicator/scale between MIN and MAX in response to a user applied force, where the relationship between the flow rate indicator/scale and the position indicator is based on calibrated flow characteristics of the balance or flow limiting valve. The user can set an exact desired flow rate in one operation by moving the knob/handle to a desired position between MIN and MAX without consulting a printed flow curve or balance calculator to determine the desired exact flow rate.
