CompaCt safety val ve for solar thermal systems r140C Descrizione The Giacomini R140C safety valves series are used in solar thermal systems using or glycol solutions (max. 50 %), with closed expansion tank, in order to guarantee that the pressure of the fluid of the circuits does not exceedthe project limits. In copliance with Directive "PED" 2014/68/UE, cat. IV.

The R140C safety valves series must be mounted in vertical positions, in order to avid the deposit of the impurities contained in the system, and in line with the sense of fliw indicated from the arrow on the body. The safety valves, moreover, must be installed in the coldest part of the system (corresponding to the solar manifolds delivery, as showed in figure), cleary visible and easy controllable. The connecting pipework of the safety valve must be a maximum of 1 m long, without any restriction, and its diameter not lower than the one of the inlet connection. The discharge of the safety valve must be cleary visible and carried in pipework with diameter not lower than one of the outlet connection. ≤ 1 m R140C R141 VES Warning. In order to avoid situations of danger for property and/or individuals, during the installation, commissioning and maintenance of the safety valves, it is important to respect all the technique norms and the indications contained in the present document. Maintenance The inspection of the valve must be carried out at least once per year, increasing the pressure of the system until the discarge. If this were not possible, the handle can be turned and the discharge controlled at sight. The eventual impurities formed on the seat can be removed by means of periodic cleaning. R140C 0425
