1.1 Scope of the Manual
This Manual has been prepared by the Manufacturer to provide the operating technical information for instal-
lation, operation and maintenance of the valve concerned.
The Manual, which is an integral part of the valve concerned, must be preserved throughout the life of the valve
in a known easily accessible place, available for consultation whenever required.
If the Manual is lost, damaged or becomes illegible, contact the Manufacturer for a copy specifying the serial
number of the valve.
If the valve concerned changes ownership, the Manual has to be handed over to the new owner as part of the
valve supply.
The Manual is meant for specialist technical personnel appointed and authorized by the Manufacturer, owner
and installer to act on the valve concerned for which specic technical skills in the sector concerned are neces-
sary (electrical, mechanical, etc.).
The illustrations may di󰀨er from the actual structure of the valve concerned but do not interfere with the expla-
nation of the operations.
In case of doubt, contact the Manufacturer for explanations.
The Manufacturer reserves the right to make changes to the Manual without the obligation to provide prior
notication, except in case of modications concerning the safety level.
The technical information included in this Instruction Manual is the property of the Manufacturer and therefore
has to be considered as condential.
It is forbidden to use the Manual for purposes other than those strictly linked to the operation and maintenance
of the valve concerned.
This information is provided by the Manufacturer in the original language (English) and can be translated into
other languages to satisfy legislative and/or commercial requirements.

Before starting with installation, a “Safety Plan” must be implemented to safeguard the personnel di-
rectly involved and those who carry out operations in the surrounding area.
All the laws must be strictly applied, especially those concerning workplace safety.
Before proceeding with installation operations, mark o󰀨 the work area to prevent access by unauthor-
ized persons.

Do not tamper with the valve concerned by using any kind of device to obtain performances di󰀨erent
from those designed.
All unauthorized changes can a󰀨ect the health of people and the integrity of the valve.
The operators have to exclusively wear protective clothing and have to be equipped with appropriate
individual protection devices for carrying out the operations and as required by the safety and work
accident prevention standards.
Before use, ensure that all the safety devices are installed and that they are working properly.

2.5 Safety prescriptions for maintenance and replacement of components
Danger - Warning
Before carrying out any operation on the valve concerned, ensure it is switched o󰀨 and disconnected
from all mains and use suitable devices to prevent the possibility of the power sources being activated
accidentally.
Maintain the valve concerned in the conditions of utmost e󰀩ciency compliant with the maintenance
plan provided by the Manufacturer.
Good maintenance apart from preserving the functional features and essential safety features over
time, will also allow extending the working life of the valve concerned and achieving the best possible
performance.
Strictly follow the procedures indicated in the Manual, especially those concerning safety.
Ensure that all the safety devices are active and working properly.
Mark o󰀨 the work area in such a manner as to prevent the access of unauthorized persons.
Replace the worn and damaged components exclusively with original spare parts, whose safety, reli-
ability and interchangeability have been undoubtedly established.
Apart from invalidation of the warranty, the Manufacturer declines all responsibility for damage to
objects and harm to persons deriving from the use of non-original spare parts or due to modications
made during repairs without express written authorization.
Do not dump polluting material (oil, grease, paint, plastic etc.) in the environment, but carry out waste
separation disposal depending on the chemical composition of the various products in compliance
with the legislation in force.
On completion of maintenance or replacement operations, before resuming production, check that no
foreign bodies (rags, tools etc.) have been left inside the valve concerned.

3.3 Operating principle
Under normal operation conditions there is no compressed air inside the valve body; allowing, thus, the owing
of the material inside the valve.
In the case of "stimulated” operation, compressed air is present inside the valve body and exerts pressure on
the sleeve, allowing the closing of the valve and, as a consequence, prevents the owing of the material.

The standard VM Pinch Valves have NOT been designed to operate in hazardous conditions or with hazardous
materials. If these conditions are met, it is compulsory to inform the manufacturer.
The materials considered being hazardous are the following:
- explosives,
- toxic,
- ammable,
- harmful and / or similar.
The applications considered being hazardous are the following:
- unloading from the silo or cells containing the materials previously indicated
3.4 Permitted use
3.5 Improper use not permitted
The VM Pinch Valve has been designed to intercept the ow of powder or granular material in pneumatic con-
veying systems and, in particular, in pneumatic systems applied to material loading from tanker.
