INSTALLATION AND MAINTENANCE INSTRUCTIONS 

 PNEUMATIC CONTROL VALVE 

ADCATROL PV25 

– PV40 

 

GENERAL 
 

 

These  instructions  must  be  carefully  read  before  any  work  involving  products  supplied  by  VALSTEAM  ADCA 
ENGINEERING S.A. is undertaken. 

 

 

The installation procedure is a critical stage in a life of a valve and care should be taken to avoid damage to the 
valve or equipment.

 

 

 

Control  valves  are  designed  to  give  accurate  control.  They  give  their  maximum  performance  only  when  the 
equipment  and  piping  associated  with  them  is  correctly  sized  and  installed  in  accordance  with  our 
recommendations. 

 

 

Referring  to  the  name-plate  located  on  pneumatic  actuator  yoke,  check  that  the  product  is  suitable  for  the 
intended use/application as follows:  

- the body material must be compatible with the process fluid 
- compatibility with the pressure and temperature and their maximum and minimum values 

 

Adcatrol control  valves are not  intended to  withstand  external stresses that may be  induced by  any system to 
which  they  are  fitted.  It  is  the  responsibility  of  the  installer  to  consider  these  stresses  and  take  adequate 
precautions to minimise them. 

 

 

Note: 
 

 

Current  regional  safety  regulations  should  be  take  in  to account and  followed,  while  doing  the  installation  and 
maintenance work. 

 

Handling, installation and maintenance work must be carried out by trained personnel. A supervisor must follow 
and check all activities. 

 

For the problems that cannot be solve with the help of this instructions, please contact the supplier or the 
manufacturer. 

 

The manufacturer reserves the right to change the design and material of this product without notice. 

 
 

 

 

 

If malfunction of any other equipment or system operation failure may result in a dangerous overpressure, over 
temperature or even vacuum condition, a safety device must be included in the system to prevent such 
situations. 

At start up, the presence of small particles in the fluid (dirt, scale, weld splatters, etc) may cause an imperfect 
closure of the seat. If this occurs, proceed to an accurate cleaning. 

Do  not  touch  the  equipment  without  appropriate  protection  during  working  operation  because  it  may  conduct 
heat if the used fluid is at high temperature. 

Before  starting  maintenance  be  sure  that  the  equipment  is  not  pressurized  or  hot.  Even  if  upstream  and 
downstream isolating valves have been closed care should be taken since fluid under pressure may be trapped 
between them. 

The equipments must be used within the working temperature and pressure limits laid down for them, otherwise 
they may fail (refer to nameplate and/or IS- Information Sheet). 

Manual  handling  of  products  may  present  a  risk  of  injury.  You  are  advised  to  assess  the  risks  taking  into 
account the task, the individual, the load and the working environment. 

Before starting work ensure that you have suitable tools and/or consumables available. Use only genuine ADCA 
replacement parts.
