Start-Up; Calibration Of The Valve - INOXPA OVERFLOW VALVE Installation, Service And Maintenance Instructions

Start-up

6. Start-up
Read carefully the instructions in chapter
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.
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.
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 fluids are circulating or when
cleaning and/or sterilization are being carried out.

6.1. CALIBRATION OF THE VALVE

Upon request, the overflow valve is shipped calibrated from the factory.
The valve calibration is performed with a flow recirculation through a bypass-type mounting. To per-
form it, it is necessary to have a pump, a gauge, a shut-off valve and the overflow valve to tare and
follow the next steps:
- operate the pump with the shut-off valve in closed position. Thus, the flow will do the recircula-
tion going through the overflow valve,
- loosen the lock nut and tighten the top nut of the overflow valve until the gauge indicates the
whished pressure in the overflow valve.
Once the valve is calibrated, it will open when the installation pressure exceeds the calibrated pres-
sure. So, the flow will recirculate to prevent the installation damage.
