In this flow data manual we have endeavoured to make the information as accurate aspossible and we cannot accept any responsibility should it be found that in any respectthe information is inaccurate or incomplete or becomes so as a result of furtherdevelopments or otherwise.

The data in this section relates to bronze fixed orifice double regulating valves (FODRV)Fig 1732L (1/2”), 1732M (1/2”), and 1732 (1/2” to 2”)..Note: Suffix L indicates low flow, M indicates medium flow and C indicates compression
end for copper pipe.The correction factors used to calculate the Kvs values for copper pipe are based on an average value of compression fittings.If other pipe materials and adaptors are used please contact the Hattersley Technical Department.
1.0 Flow Coefficient Kv/KvsNote: Kv relates to the FODRV’s pressure loss whilst Kvs relates to the signal across
the orifice for flow measurement.
Kv = Kvs = Q where Q = flow rate m3/h.√∆P ∆P = differential pressure in bar.
2.0 Kvs Values - Flow Measurement
3.0 Kv Values - FODRV - Full Open
4.0 Kv Values - FODRV - 25% Open

5.0 Valve Sizing
The design method for sizing components is to establish firstly, the mass flow rateneeded to carry the required amount of heat to a zone and secondly, to relate this to anappropriate flow velocity or pressure loss per unit length. A pipe size can then be selectedand all components are line size.
In the case of metering stations and DRV’s the same rule applies because their design isbased also on appropriate flow velocities and pipe pressure losses.
As the power of the pump is determined from the index circuit, it is of no consequencewhat the head loss is through the DRV’s other than fully open.Note that the delivery of the pump is based on the requirement of the complete system.
6.0 ß Ratio
The ß ratio is the ratio of the orifice diameter to pipe bore diameter and this has beencarefully selected for each metering station to minimise the effects of variations in internalbores or where an incorrect grade of pipe has been used and to cater for lower velocitiessometimes encountered in smaller pipe sizes.
7.0 Installation
Straight Pipe Lengths
It is important that there should be minimum of 5 diameters of straight pipe upstream and 2 diameters of straight pipe downstream, without intrusions, of the Fig 1732 for repeatable performance.
Less than these diameters will increase inaccuracy to an unacceptable level, the valueof which is unpredicable as it is not a stable value.
