SN/NRV Check Valve is uesd on the piping of liquid,suction gas or hot air on the freezing,cold storage and air conditioner units.
The valve seat and seals have execllent sealing performance.Both threaded and welded connections are available for us.
◆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 damping piston that makes the valves suitable for installation in lines where
pulsation can occur,e.g.in the dischange line from the compressor.
