Capped valves CSV..SHP series

The capped valves are classified as “Pressure accessories” in the sense of the PED Directive 2014/68/EU, Article 2, paragraph 5 and are subject of Article 4, paragraph 1, letter (c), of the same Directive. All the product range is suitable for use with refrigerant R744 (CO2), classified in Article 13, paragraph 1, letter (b), of PED Directive 2014/68/EU as part of Group 2, therefore not toxic, not inflammable and not explosive fluid and indicated in A1 Group of Annex E of standard EN 378-1.


The valve body is made of hot forged brass EN 12420 – CW617N and the spindle is made of galvanized steel. A package consisting of EPDM seals and aramid fibers gaskets, approved by DIN-DVGW in accordance with DIN 3535, part 6 FA, guarantees an excellent seal to the outside between the spindle and the gland; instead, the seal between the spindle group and the body, in direct contact with the fluid, is ensured by an HNBR.


Read carefully the installation instructions included in the box. For the CSV..SHP types is necessary to disassemble the valve, acting on the indicated hexagon, before brazing the body to the system. The brazing shall be done with a low melting point alloy. During this process do not point the flame directly towards the body in order to prevent leaving combustion residues on the sealing seats.
