ONE 7TS – Safety and accident prevention
Operation
The valve consists of a ball which is kept in position by a spring that lets it open when pressure exceeds the
value entered during the final testing phase.
This preload must not be altered to avoid changing the valve opening value. Failure to comply with this re-
quirement affects the safety conditions and shall immediately invalidate the warranty; for this reason a seal
has been placed on the spring preload regulation nut.
If the preset pressure value is exceeded the valve opens automatically and discharges the product from the
outlet pipe; the valve will close once the pressure is back within the required value, so the pressure regulator
must be adjusted to reduce the pressure value in the compression head until the valve closes, or in the case
of piston pumps the speed must be reduced.
Once the overpressure valve is closed, you can increase the homogenizing pressure back to the required
working level, unless the event that cause the valve to open has caused damage to it and immediate stop is
required.
ATTENTION:
You should ALWAYS point the discharge pipe down, to avoid hazard for operators; the customer is
required to place a funnel for collecting outfed product and convey it to a drain
ATTENTION:
Ensure that the discharged product is disposed of in compliance with current regulations in force in
the country where the machine is installed.
ATTENTION:
Repeated triggering of the overpressure valve leads to damage of the seal with consequent reduc-
tion of the opening value entered in the calibration phase. It is therefore important to periodically re-
place the seat and ball to restore the original operating conditions.
Washing
Washing of the part in contact with the product will normally take place during the machine washing proce-
dure (C.I.P.).
ATTENTION:
Every time the valve is triggered because the preset pressure value is exceeded, you MUST ALWAYS
remove the valve from its position and wash it manually.
ATTENTION:
Do not disassemble the valve body nor remove the plastic cover. It is prohibited to alter the setting of
the safety valve without prior written authorization from Niro Soavi as this will affect the safety of
machine, components and operators; failure to observe this instruction will invalidate the guarantee.
