FLOW RATE SCALE FIELD CALIBRATION FOR BALANCING VALVE

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...

Beschreibung
Zusammenfassung:	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.
