Check valves, back-shut-off valves NDV, SCA-X, etc.

Check valves are designed to prevent the reverse flow of the medium, hermetically closing the passage in the opposite direction of flow.

Type 223 - brass spring check valve with external thread and axial gate. It is characterized by low hydraulic resistance, does not create conditions for the occurrence of hydraulic shock.

223. Technical description.

NDV - cast iron flanged spring check valves with axial closure. They are used in water supply systems, water distribution, pumping stations, industry, heat supply within the operational characteristics.
Models: NDV 402, NDV 462, NDV 802, NDV 812, NDV 805, NDV 895.

Check valves NRV and NRVH are installed in liquid lines, suction lines and hot gas pipelines of refrigeration units and air conditioning systems operating on fluorinated refrigerants. The valves guarantee the movement of the refrigerant flow only in the specified direction and prevent the reverse condensation of the refrigerant. The NRV and NRVH valves have a built-in damping piston that allows the valve to be installed in lines with pressure pulsation, for example, in the discharge line behind the compressor.

NRV EF valves are characterized by moderate hydraulic resistance, do not create conditions for the occurrence of hydraulic shock. The NRV EF check valve is designed to prevent the reverse movement of the medium.

Check valves NRVA designed for installation on liquid, suction lines, as well as on hot gas supply lines, in refrigeration units and air conditioning systems running on ammonia.

Check valves of the NRVS type do not have damping properties and therefore can only be used in liquid lines.

The back-shut-off valve SCA-X, CHV-X (modifications SCA-X SS, CHV-X SS) is used in cooling systems with all common fluorinated refrigerants, ammonia, CO2, as well as with combustible hydrocarbon refrigerants (propane, butane, isobutane, ethane).
