    Abstract: A balance or flow limiting valve features a valve body/member (12) having a flow rate indicator/scale (44) 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 (48) 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 (44) 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.

    Abstract: A valve includes a body having upstream and downstream ports, both ports configured relative to a common axis, and includes a ball arranged to rotate relative to the common axis between open and closed positions to allow for fluid flow/non-fluid flow. The ball has a calibrated member having a calibrated orifice that has a flow coefficient, pressure taps located upstream and downstream of the calibrated orifice and in communication with the upstream and downstream ports respectively to measure upstream and downstream pressures when in the open position, the upstream and downstream pressure taps are angled relative to the common axis, so conditions of fluid flow are determined based on a measured pressure differential between upstream and downstream pressure taps relative to the flow coefficient of the calibrated orifice when in the open 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.
