Parameters of valve body assembly [2]Kennwerte des Ventils

characteristic of a signal or a physical output variable as response to a linear signal or physical input variable

pressure ratio at which the cavitation is acoustically detected

pressure differential ratio factor of a control valve installed without reducers or other fittings

diameter of the cross section of a seat

flow coefficient Cv in the event of a full cross-section at loss of trim

flow coefficient Cv in the event of a device failure

flow coefficient Kv in the event of a full cross-section at loss of trim

flow coefficient Kv in the event of a device failure

highest ratio that theoretically can be achieved between the maximum and minimum flow rate let past by a valve

category of valves, all of which are intended to comply with a set of specifications regarding leakage

highest actuating force that a valve can bear without permanent damage

greatest required force that has to be applied to a valve between its end positions

lowest actuating force to overcome the breakaway force of a valve

rated flow coefficient, that is expressed by a manufacturer specific designation

@number of linear limit stops

liquid pressure recovery factor of the valve without attached fittings

number of US gallons of water, within a temperature range of 40°F to 100°F, that will flow through a valve in 1 min when a pressure drop of 1 psi exists

volumetric flow rate of water in cubic metres per hour (capacity) through a valve at a rated travel at the static pressure loss across the valve of 100 kPa (1 bar), within a temperature range of 278 K to 313 K (5°C to 40°C)

maximum travel of a valve expressed in a length dimension

standard on which the leakage class/rate is based
