Each valve is supplied with an original copy of the calibration report; this document contains not only the technical data of the valve, but also the serial number (also shown on the top of the handwheel fixed to the valve body). The document is printed and validated by the INAIL technician who witnessed the calibration operation. The user is responsible for maintaining the safety valve calibration, avoiding any type of intervention that could alter its correct functioning.  Calibration  NOTE. The calibration report must be stored with care; copies cannot be issued if the original is lost. When the thrust of the pressurised fluid triggers a return spring on the disc, the valve discharges a specific amount of fluid to prevent the defined pressure level from being exceeded, and then re-closes within the permitted closure range.  Operation  Installation Before installing the R140D safety valves, the personnel in charge must size them correctly, in accordance with the current The safety valves must be installed in the highest part of the heat generator, or on the delivery pipe, no more than 1 m distance from the generator. They must be clearly visible and easy to check. The pipe connecting the safety valve to the generator must be free of any interception and with a diameter no less than that of the valve itself. The safety valve drainage must be clearly visible and channelled into a pipe with a diameter no less than that of the valve itself, using a funnel (R141 or R141C) if necessary.

The safety valves can be installed vertically or horizontally, but not upside down (to prevent system impurities from settling); respect the flow direction indicated by the arrow on the body. The valve must be checked at least once a year, by increasing the system pressure to induce drainage. If this is not possible, is possible to rotate the knob and check the drainage visually. Any impurities that form on the housing can be removed by means of regular purging.  Maintenance
