Valves

Technical data

The following formula constitutes the relationship between all the aforementioned elements:

Q = 28,3 Kv

√

p (p1 -

where

= flow [nl/min]

= valvular coefficient of the H2O valve [nl/min]

= p1 - p2 = fall in pressure between upstream and downstream [ bar ]

= absolute pressure upstream [ bar ]

28,3 = conversion coefficient from water to air

So: the capacities calculated with the given formula differ little from those that can be obtained from the flow characteristic of the
corresponding valve.
Furthermore, it also provides confirmation, from the characteristic itself, of the limits of validity of the formula.
It is only valid for

p <

p1; i.e. only up until the fall of pressure across the valve reaches a value equivalent to half the absolute

supply pressure.

In this condition the air reaches max. velocity (critical velocity

) and consequently maximum capacity

Qmax

For

p <

p1, the pressure energy is converted into kinetic energy with an increase in velocity and consequently capacity. For

p <

p1, the extra pressure energy is no longer converted into velocity energy, but dissipated in local turbulences in the form

of heat.

All of this is confirmed by the flow characteristics.
From the same characteristics it is possible to discover that that the value of the flow with

p = 1 bar is

2/3 Qmax.

The capacity corresponding to

p = 1 bar is defined

“NOMINAL FLOW Qn”.

In the case of a valve, a different flow characteristic exists for each absolute supply pressure, and thus corresponding values for
Qmax. and Qn.
Falls in pressure of

p > 1 bar are too economically onerous, and for this reason it is advisable to limit the falls in pressure to

= 0,5 bar, by choosing a larger size valve.

In the catalogue reference is normally made to the nominal flow, but the flow characteristics and the valvular coefficient are also
provided.
Let’s calculate, for example, the flow of a valve with Kv = 12 NL/min, P

= 6 bar,

P = 0,5 bar

= 28,3*12

√

0,5 (7-0,5) = 612 [Nl/min]

= 831 [Nl/min]

Q max = 1118 [Nl/min]

Pressure (bar)

Flow of the valves:

The quantity of compressed air that can flow through the
valve depends on the size of the orifices and the type
of course that must be followed within the valve itself by
the fluid under pressure. The flow of a valve is measured
using suitable measuring circuits with the hypothesis that the
upstream pressure is constant and that quantity of air required
downstream is variable.

Curves known as “

FLOW CHARACTERISTICS

” are drawn,

which indicate how the flow of the valve varies with the varia-
tion in downstream pressure, with a constant pressure supply.

Once these characteristics are known, the flow of the valve
is also known in all working conditions.

These curves show how the study model adopted for a valve
- which consists of comparing it with a converging nozzle that
releases a compressible gas with constant upstream pressure
- is reasonably valid. Indeed, according to this model, the flow
that passes through the nozzle depends on the following fac-
tors: the upstream pressure, the difference in pressure

and

the valvular coefficient

Kv.

The coefficient

summarizes the characteristics of the inter-

nal passages of the valve and is represented by the

“number

of litres of water that flow through the valve in one minute,
in normal conditions (atmospheric pressure, 20 °C) in the
presence of a fall in pressure

p [AS1]= 1 bar.
