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

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 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.
