Series BLR / NRV check valves are used for liquid, suction gas or hot air pipelines in refrigeration and air conditioning systems. Excellent quality of connections and fixings Properties: - For refrigerants containing fluorine. - When the cooling system is partially loaded, problems with system pulsation can be avoided. - Redundant connections provide flexibility in use. - They prevent refrigerant from getting into the cold part of the system. - Ensures the correct flow direction and prevents it from reversing. - Built-in damping piston makes the valves suitable for installation in lines where pulsation may occur, e.g. in the distribution line from a compressor.

One of the most important elements of the refrigeration and air conditioning system are various types of valves. Correctly selected and applied, they make the operation of the cooling or air-conditioning system correct, and its possible repairs and inspections can be carried out efficiently and economically. They also allow for easy control and regulation of the entire system. We offer a wide range of parts for the construction, maintenance and service of refrigeration and air conditioning systems. We invite you to contact manufacturers of equipment and installations, wholesalers, shops and services: refrigeration and air conditioning.

Check valves are used in refrigeration and air conditioning systems to prevent backflow of refrigerant in the event of, for example, self-regulation, or a sudden increase or drop in pressure on one side. It can be especially dangerous in the case of refrigerant getting into the compressor's working space. This can result in the failure of the entire system and the need to replace the compressor.
