ART 22
Technical Data
The Albion ART 22 is a fixed orifice double regulating valve used to regulate and
measure the flow passing through it.
Flow Coefficient
The flow rate can be calculated using the Kv value and a measured signal.
Kv = Q*36 Kvs = Q*36
√ ∆P √ ∆Ps
where Kv &Kvs = flow coefficient (m3/hr at 1 bar differential)
Q = flow rate (l/s)
∆P = headloss attributable to valve (kPa)
∆Ps = differential pressure across tappings (signal) (kPa)
Kvs Values
Size ½”L ½”ML ½” ¾” 1” 1¼” 1½” 2”
Kvs 0.62 1.1 2.3 5.3 9.2 19.0 22.1 42.3
Pressure Loss
The pressure loss across the fixed orifice double regulating valve is the combined
loss attributable to the orifice plated and double regulating valve in the fully open
position.
Kv Values
Size ½”L ½”ML ½” ¾” 1” 1¼” 1½” 2”
Kv 0.533 0.738 2.00 3.88 7.28 13.39 18.69 30.10
Installation
Fixed orifice double regulating valves must always be installed with a minimum of
5 pipe diameters of straight pipe, without intrusion, upstream of the orifice plate.
Downstream of the valve a minimum of 2 pipe diameters of straight pipe are
required.
Sizing
Once the required flow rate has been calculated, the size of the fixed orifice
double regulating valve can be determined based on the following:
The minimum signal at the design flow rate of 1 kPa.
For minimum pressure loss, a maximum signal of 4.7 kPa, which corresponds
to the maximum differential pressure range of a fluorocarbon manometer.
