Typical applicationsTemperature controlTo control the flow of primary heating fluid, whether steam orhot water, to provide constant secondary temperature.Application shows the use of pneumatic power (1)and electronic intelligence (2) on a steamto liquid heat exchanger.

Pressure controlTo control steam, water or air distribution lines atprecise operating levels. The system shown is acomplete pneumatic controls package using acontroller (1) with pneumatic valve and positioner (2).

Flow controlUsed in conjunction with flowmeters to accurately

control the flow of steam, gases or liquids. The example shows the use of an

electronic controller (1) signalled from a DP cell (2).The controller delivers an electronic output to an

electro-pneumatic positioner (3) on the valve actuator (4).

Control valve sizing and selection

Kv selection exampleSteam demand of heat exchanger = 700 kg / h of saturated steamSteam pressure upstream of valve = 5 bar g or 6 bar absSteam pressure required in exchanger = 4 bar g or 5 bar absValve pressure drop = 6 - 5 = 1 bar

Draw line at 700 kg / h flowrate (A - B) and from 6 bar abs inletpressure to the 1 bar pressure drop line (C - D)Drop vertical line (D - E) to meet the 700 kg/h flow line and read the Kvvalue at the crossing point (F) i.e.: Kv = 16For valve size refer to step 2 below.

Saturated /superheated steam sizing chartThis sizing chart is empirical and should not be used for critical applications

Step 2 Determine the valve size

Step 1 Determine the valve K vKv calculation is an iterative process requiringknowledge of valve dynamics, piping geometryfactors, and outlet velocities.

In practice, the sizing chart below is based onempirical values and will cater for most applications.

A Kv of 16 requires a standard valve size of DN32To select the correct valve turn to next page for step 3
