INSTALLATION AND MAINTENANCE INSTRUCTIONS
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.
