4. General Information
The overow valve 74700 is a valve with a sanitary design operated by springs. It protects the facili-
ties from possible overpressures.
The valve is calibrated to a specic pressure by the pressure nut. This pressure is the safety maxi-
mum pressure to avoid damage to the facility. Under working standard conditions, the valve remains
closed. If the circuit pressure exceeds the calibrated pressure, the valve is opened, allowing the ow
to pass and reducing the pressure facility.
The valve can incorporate a handle designed to allow the valve remains partially open. Thus, during
the CIP process, the cleaning products can pass through the valve.
4.1. DESCRIPTION
4.2. APPLICATION
The overow valve 74700 is a valve used to perform bypass as a relief measure to protect lines,
pumps, accessories, tanks, etc. of the dairies, food, beverage, pharmaceutical or chemical indus-
tries.

6. Start-up
Read carefully the instructions in chapter 5. Installation before start-up the valve.
Before putting the valve into service the following must be taken into consideration:
- check that the piping and valve are completely free of possible traces of welding slag or other
foreign particles. Clean the system if necessary,
- check that the valve moves smoothly. If necessary, lubricate it with special grease or soapy
water,
- check for possible leaks, and make sure the pipes and their connections are sealed and do not
have any leaks,
- in the case of the manual valve, actuate the valve.
Before start-up, the persons in charge must be duly informed about how the valve works
and the safety instructions to follow. This instruction manual will be available to person-
nel at all times.
ATTENTION
Do not modify the operating parameters for which the valve has been designed without
prior written authorisation from INOXPA.
¡Burn hazard! Do not touch the valve or the pipes when hot uids are circulating or when
cleaning and/or sterilization are being carried out.
6.1. CALIBRATION OF THE VALVE
Upon request, the overow valve is shipped calibrated from the factory.
The valve calibration is performed with a ow recirculation through a bypass-type mounting. To per-
form it, it is necessary to have a pump, a gauge, a shut-o󰀨 valve and the overow valve to tare and
follow the next steps:
- operate the pump with the shut-o󰀨 valve in closed position. Thus, the ow will do the recircula-
tion going through the overow valve,
- loosen the lock nut and tighten the top nut of the overow valve until the gauge indicates the
whished pressure in the overow valve.
Once the valve is calibrated, it will open when the installation pressure exceeds the calibrated pres-
sure. So, the ow will recirculate to prevent the installation damage.
