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 gauge pressure value at the device inlet to which a pressure reducing regulator or a back pressure regulator can be adjusted and still remain within the specified performance limits
highest gauge pressure value at the device outlet to which a pressure reducing regulator or a back pressure regulator can be adjusted and still remain within the specified performance limits
lowest gauge pressure value at the device inlet to which a pressure reducing regulator or a back pressure regulator can be adjusted and still remain within the specified performance limits
lowest gauge pressure value at the device outlet to which a pressure reducing regulator or a back pressure regulator can be adjusted and still remain within the specified performance limits
rated flow coefficient, that is expressed by a manufacturer specific designation
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
gauge pressure value at the device outlet to which a pressure reducing regulator or a back pressure regulator is adjusted
