VCP Pressure Relief Valves consist of a cylindrical casing with a bottom ange to be connected with a spigot
welded on the silo roof, a disc shape inner steel lid for negative pressure operation held in position by a cen-
tral spring rod, an outside steel ring for excess pressure kept in position by three spring rods, gaskets, and a
weather protection cover.
In the VCP Pressure Relief Valve, helical springs keep the valve lids closed when the pressure value remains
within the preset limits. The three outside spring rods keep the external ring-shaped lid rmly closed as long
as the force generated by the pressure inside the silo does not overcome the spring force. Once the pressure
exceeds the preset value the lid is pushed up and the pressure can escape. The smaller lid covers the central
circular opening of the external lid from below. It is held in the middle by a single spring rod and is pressed
onto the external lid by the normal air pressure inside the silo. In the event of suction pressure, the spring is
compressed and allows the lid to drop. The air entering the silo from outside ensures rapid pressure balance
and pushes the central lid back up into the “closed” position
Important
The terms “equipment” and “valve” used in this manual refer to the same machine.
As components meant for installation in a plant, the valves - not fully provided with safety means -
have to be considered “partly completed machinery”. Therefore, they do not bear an EC marking.
It is forbidden to start the valve unless the machine/plant in which it is to be installed has been de-
clared compliant with the Directive 2006/42/EC and further modications.

3.4 Permitted use
These valves are specially designed for use with powder material and granules. The Manufacturer shall not
be liable for any other use.
The valve is designed and manufactured so as to avoid abnormal overheating during operation. The valve
must be installed with enough space around it to allow assembly/disassembly, cleaning and maintenance
operations.
If the valve is to be used with very hot materials, such that the surface temperature exceeds 60°, the installer
must provide for insulating of the valve or installing mechanical barriers to prevent access to very hot parts;
there have to also be applied on the valve the necessary warning signs or pictograms that indicate these risks.
The VCP valve has the following features:
- The valve body can withstand an overpressure P=1bar (10000 mm H20, 100Kpa)
- The paint coating of the valve disc (if present) is < 200 micron thick.
- The valve body is provided with a ange and it can be connected directly to the silo.
- However, a spigot is provided to be welded to the silo, where the valve will then get bolted.
Once assembled, the valve ensures sealing against dust.
The use of valves in the presence of dust with features more severe to what previously indicated or in areas
with di󰀨erent classication, is directly and exclusively under the liability of the user.
The VCP Pressure relief valve food version (model GF), compliant to EC 1935/2004, are suitable for applica-
tion with E simulant, max. temperature of 80 °C and 3 days constant in-contact time.
3.3 Operating principle
The Spring-Loaded Pressure Relief Valve are used in all plants where it is required to control excess pressures
or negative pressures, if any, that may be created inside the containers, thereby preventing their breakage or
deformation.
The VCP valve is not controlled by an external device.
It starts working automatically whenever there is a pressure imbalance within the silo due to lling or emptying
of the silo by means of any system. (UNI ISO 8456 5.1.1.4.2 and 5.1.1.4.3).
Size 375 complies to HSE (0- 9540853-0-2).
NOTE: Appropriate maintenance as described in the relevant section of this Manual will considerably increase
the life duration of the valve. This is particularly important when the material handled tends to harden
or get compacted due to shut downs for a certain period of time.

3.5 Improper use not permitted

Danger - Warning
Uses not permitted: the valve must be used only for the specic purpose envisaged by the Manufac-
turer.
Specically:
- do not use the valves if they have not been installed correctly in accordance with the standards in force.
- do not use the valves if the gaskets are not intact.
- do not use the valve as a support even if it is not in operation. In addition to falling, there is risk of damage
to the valve.
The plant installer/installation technician is responsible for providing and installing all the safety devices to
avoid damage to objects or persons in case of breakage and falling of pieces.
WARNINGS
1) The Manufacturer shall not accept liabilities related to the safety of the personnel or damages to objects or
valve failure unless if the operations involving loading/unloading from trucks, transport, positioning at the
site, use, repairs, maintenance, etc. have be carried out in compliance with the warnings described in this
Manual. Likewise, the Manufacturer shall not accept any responsibility if the valve is used:
- improperly;
- by unauthorized persons or those not suitable trained for the job;
- with modications to the original conguration;
- with spare parts that are not original or are not specic for the model;
- non conforming to the standard and legislation currently in force;
- not conforming to the recommendations in this Manual.
2) Before carrying out any operation, the user must make sure the work area is clear of obstacles (persons or
machines) which represent potential sources of danger.
3) Operations involving lifting, transport, installation at the site, commissioning, checking the stability and
working, routine and extraordinary maintenance, etc. must be performed by qualied, authorized personnel
who must operate in accordance with the indications given in this Manual and in compliance with the safety
regulations in force.
4) When installing the valve, it must be connected to the earth wire.
5) It is forbidden to carry out maintenance, repairs or modications while the valve is running. Before carrying
out any operation, disconnect all the electrical and compressed air supplies that may be connected directly
or indirectly to the valve.
6) Before installation of the VCP valve, the plant technician/installer must check the pressure and negative
pressure for which the VCP valve has been calibrated (values indicated on the rating plate) to make sure
these suit the limits tolerated by the container on which the valve is to be applied.
7) Installation of the VCP valve by the installer/plant technician must be done according to the indications given
in this Manual. The installer/plant technician must carry out the functional check as well as the adjustment
and checking of the correct positioning.
8) Disassembly/assembly operations, if any, of the valve are only performed for maintenance and/or cleaning
and they must be carried out only by authorized persons qualied for such operations: the indications nec-
essary for disassembly of some parts of the valve are enclosed to the User manual.

9) Every time the calibrated pressure value is exceeded, the valve will open and release an air-dust mixture (a
dust cloud) to the outside, but only during the activation phase due to overpressure. The VCP valve is suit-
able for use on pressurized or vacuum containers not subjected to special testing or legislation.
The only function of the valve is to safeguard containers, lters and other equipmets from overpressures or
negative pressure outside the tolerance limits.
Specic type of valves are required to safeguard the operator or the environment impact.
10) Make sure the material handled inside the container is not hazardous: according to standard UNI-EN
626-1 § 3.2, any chemical or biological agent that endangers the health is classied as being a hazardous
substance, because:
- highly toxic;
- toxic;
- harmful;
- corrosive;
- irritant;
- sensitizing;
- carcinogenic;
- mutagens;
- teratogenic;
- pathogens;
- asphyxiating.
The user/plant technician must provide the necessary measures while using the VCP with hazardous sub-
stances to reduce atmospheric emissions in accordance with standard UNI-EN 626-1 Appendix A.2. This situ-
ation occurs rarely; however, the installer/plant technician must delimit an area around which personnel is not
allowed during pressurized loading of the silo.
11) This Manual requires setting the entire plant in safety condition before acting on the VCP valve.
NOTE: Remember that, to avoid or reduce futile activation of the valve:
- The permitted pressures must be followed during silos loading phase. The recommended pressure
values must stay lower than 1.5 bar, according to the standards in force.
- The valve maintenance shall be carried out as indicated in the User Manual.
- Install properly sized lters.
- The lters must be submitted to maintenance according to the indications given by the manufacturer.
- The VCP valve must be installed at the top of the silo.
For assembly, maintenance and cleaning, the operator/maintenance personnel must use suitable means, for
example: overhead work platforms, fall preventing devices for personal protection, etc., meant to carry out the
operations required in complete safety.
The VCP valves are not suitable for applications with liquids or uid di󰀨erent from atmospheric air.

For the exact identication of the valve concerned, see the identication plate.
The shipping document shows the diameter of the Spring-Loaded Pressure Relief in addition to the serial
number and identication codes.
Information regarding the technical features of the VCP Spring-Loaded Pressure Reliefs, such as diameter and
seal and disc characteristics is given in Chapter 10.
The only source of noise on the valve is due to the air that passes through during operation.
The VCP valve is usually installed on the top of silos, i.e. in places where exposure of operators is limited. Dur-
ing maintenance, the plant must remain stationary, so there is no noise from the valve. Because of the limited
frequency (occasional) of valve operation and the distance of the operators, risks due to noise are excluded.
Danger - Warning
Depending on the installation site, the installer must adopt suitable systems (barriers, etc.), if neces-
sary, to maintain the noise levels within the legally permitted limits.
3.7 Environmental operating limits
Unless otherwise specied, the valve concerned may be used only within the limits indicated.
- Altitude: less than 1,000 m at sea level
- Environmental temperature: between - 20 °C and + 40 °C
- Cold climates: with temperature less than 5 °C use oil and lubricants suitable to the operating temperature.

Extraordinary access is provided for removing foreign bodies and material deposits from inside the valve or for
extraordinary maintenance.
For accident prevention it is essential to keep the valve out of personnel reach during operation. To this pur-
pose, the customer has to provide suitable safety devices such as grids, as well as protective inlet and outlet
joints (either robust exible sleeves or rigid pipe unions). However, the installer has to avoid that, even inad-
vertently, a person remains harmed (by employing suitable hopper, safety grilles,...).
When using movable safety devices, provide protection limit switches, which stop the valve instantaneously
if the protection is opened or removed. Restarting of the valve must only be possible when the protection is
e󰀨ective again (according to EN 1088).
