CompaCt safety val ve for use in domestiC wa ter systems r140C-1

Description

The R140C-1 safety valves are used in domestic water systems to protect the hot water accumulation, and can also be used to drain cold water. The valves comply with Directive “PED” 2014/68/UE. The user must respect the calibration of the safety valves (set by the manufacturer and indicated on the coloured cap), avoiding any type of intervention that could alter their correct functioning.

  • Washer: steel Installation The safety valves of the R140C-1 range must be assembled vertically (to prevent system impurities from settling), respecting the flow direction indicated by the arrow on the body. They must be installed in the coldest part of the system (in line with the domestic water accumulation delivery, as shown in the figure), clearly visible and easy to check. The transfer pipe to the safety valve must be max. 1 metre long, without any reduction element and with a diameter no less than that of the input section of the valve itself. The safety valve drainage must be channelled into the funnel with visible drainage - R141, R141C series. ≤ 1 m R140C-1 BS1-BS2 R141 Warning. During the installation, initial start-up and maintenance of the safety valves, it is important to respect all good technical practices as well as the indications given in this document in order to avoid dangerous situations for people and/or objects. 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. R140C-1 0425

Relief funnel R141 Relief funnel R141C For safety valve with drainage of: R141Y014 R141CY004 3/4" Note. The use of the R141, R141C relief funnels (plus curved couplings R19 and R189 if necessary) prevents any spray from reaching the electric components.
