7.0 PERIODICAL OPERATIONS
24 hours after the first commissioning, control the connections to the pipe and verify the tightening of the flange
bolts. Inspect the valve every year by verifying its wear and replacing any damaged parts.
Periodically verify any phenomena of internal and/or external corrosion and/or erosion as they may significantly
damage the pressurized parts by locally reducing the thickness and as a consequence the safety degree.

ATTENTION!!!
The OMC valves are univocally identified by a serial number fixed on the plate located
on the actuator’s yoke. To order any spare parts or for any other need, always refer to the above-
mentioned number
.
9.0 PRESSURE/TEMPERATURE RELATIONSHIP
For the pressure regression in relation to the temperature refer to the document:
- OMC-TUV-00
The actual use of the valve depends on the combination of the materials of which it is made up.
