Operation
The valve is composed of a ball held in position in its seating by a spring which allows it to open only
when the load on it exceeds its factory setting.
The spring loading should not be changed as this would modify the valve opening value and cause
the immediate forfeiture of the safety conditions established by
GEA Niro Soavi
and the guarantee.
Therefore a seal has been applied to the spring preload adjustment nut.
In the event the calibration setting is exceeded, the valve opens automatically and lets the product
flow out of the discharge pipe; it closes again when pressure reduces below the opening value.
Therefore it is necessary to use the pressure regulating device to decrease the pressure in the
compression head until the valve closes, or reducing the pump speed in case of piston pumps.
Once the pressure relief valve has closed again, normal operating pressure can be re-established,
provided the machine has not been damaged such as to cause an immediate stop.
CAUTION:
The discharge pipe must ALWAYS be directed downwards to avoid harming the operator; the
Customer shall be responsible to install a funnel to collect the outcoming product and carry
it to the drainage system
CAUTION:
Dispose of ejected product properly according to local legislation.
CAUTION:
The valve seat of the pressure relief valve is damaged to some extent each and every time
the valve blows. This will lower the pressure setpoint of the safety valve. Therefore it is
periodically necessary to replace the seat and ball to recover the original setpoint conditions.
Washing
The part in contact with the product is normally cleaned during machine washing (C.I.P.).
CAUTION:
It is ALWAYS necessary to disassemble the valve from the compression head and clean it
manually after any overpressure relief valve discharge.
CAUTION:
Do not disassemble the valve body nor remove its plastic cap. Changes to the safety valve
setting are not allowed and shall invalidate the guarantee and affect protection of the machine,
of its components and of the operators, unless a written authorization has been obtained
from GEA Niro Soavi.
