Description

The Giacomini safety valves of the R140, R140M range are used to avoid overpressure on the heat generators of the heating system, domestic water system (protecting the hot water accumulation) and water systems (cold water drainage). The valves comply with Directive "PED" 2014/68/UE.

They can also be used to drain off cold water in water systems. They are factory-calibrated and the drainage pressure value cannot be altered. Installation Before installing any safety valve, the technical personnel in charge of the system must size it correctly, in accordance with the current regulations. The safety valves must be installed in the highest part of the heat generator, or on the delivery pipe, no more than 1m 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. Warning. The safety valves can be assembled vertically or horizontally, but not upside down (to prevent system impurities from settling); respect the flow direction indicated by the arrow on the body.

r140, r140M Performance The Giacomini R140, R140M valves comply with the "R" collection regarding the safety of devices containing hot pressurised liquids: "In the case of heating systems for water destined for consumption, the expansion system that protects the container can be made with a vent valve (i.e. a valve with a counter-weight or spring, whose hole diameter - in mm - is no less than √ V/5 where V is the volume - in litres - of the heater, and anyway minimum 15 mm).

r140, r140M Accessories It is a good idea to channel the fluids drained by the safety valves with the aid of a funnel R141 or R141C (to be ordered separately). Relief funnel R141 Relief funnel R141C For safety valve with drainage of: R141Y003 - 1/2" R141Y014 R141CY004 3/4" R141Y015 R141CY005 1" R141Y016 R141CY006 1 1/4" Note. The use of the R141 relief funnels (plus curved couplings R19 and R189 if necessary) prevents any spray from reaching the electric components. Maintenance The valve must be checked at least once a year, by increasing the system pressure to induce drainage. If this is not possible, you can rotate the knob and check the drainage visually. Any impurities that form on the housing can be removed by means of regular purging.
