The receiver valves are classified as “Pressure accessories” in the sense of the Directive PED 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 fluids proper to the Group 2, as defined in Article 13, paragraph 1, letter (b) of Directive PED 2014/68/EU, therefore not toxic, not inflammable and not explosive fluids; to this macro Group belongs also the refrigerant fluids listed and classified in A1Group of Annex E of standard EN 378-1. Examples of refrigerant fluids are:
– HFC R134a, R404A, R407C, R410A, R507;
– Blends HFC/HFO, R448A, R449A, R450A, R452A, R513A.
This valve series is particularly suitable to intercept fluid in the liquid receivers.
The body is made of hot forged brass EN 12420 – CW617N and the spindle is made of galvanized steel. In order to avoid leakages, the applied gaskets in the valves are made of special sintered graphite.
For the RVV..S / RHV..S series, the connection to the system shall be made with a low melting point alloy. During welding, avoid directing the flame directly towards the body in order to preserve the integrity of the gaskets.
