◆For flourinated refrigerants
◆Resonance problems can be avoided at partial load in the refrigeration plant.
◆Oversize connections provide flexibility in use.
◆Prevents refrigerant from warm to cold system part.
◆Ensures correct flow direction and avoid reversal.
◆Both straightway and angleway versions
◆Built-in dampingpiston that makes the valves suitable for installation in lines where pulsation can occur,e.g.in the dischange line from the compressor.
