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 seal used in the valves and directly in contact with the fluid is made of special sintered graphite which is practically chemically inert to all the refrigerant fluids listed above.


For the RVV..S / RHV..S series the brazing to the system shall be done with a low melting point alloy. During this process do not point the flame directly towards the body in order to save the gaskets.
