62.1 n Functional features n CARLY advantages Check valves CRCY / CRCYP (high Pressure) n Applications • The check valves ensure a one-way direction of the refrigerant flow, in refrigerating and air conditioning installations. • The CRCYP high Pressure check valves are fitted with a more powerful spring and are to be installed on the discharge line of compressors coupled in parallel. C o Products are compatible with HFCs, HCFCs, CFCs, as well as with their associated oils and additives. Products are designed for use of non-hazardous refrigerants from group 2 of PED 97/23/EC. o Product classification in CE categories is performed using the PED 97/23/EC table, corresponding to a nominal diameter-based selection. o An arrow indicating the refrigerant flow direction is engraved on the brass body of the valve. o 10 models with SAE connections to screw, except for model 3/4” which is a BSP threading (from 1/4” to 3/4” and from 6 to 18 mm). o 24 models with connections to braze (from 1/4” to 7/8” and from 6 to 22 mm). o For use on the discharge line of compressors coupled in parallel, select the CRCYP high Pressure models, with more powerful springs and with connections identical to those of standard check valves. o The check valves can be installed in all positions. o They are equipped with an internal pulse absorber piston, with PTFE gasket. o Pressure drops are negligible. o Perfect air tightness ensured by a TIG brass weld of the body. o Check valves with connections to braze do not require removal, thanks to long length sleeves made of copper-plated brass up to model 5 S/MMS, and made of copper for models 6 and 7 S/MMS. o GOST certified products .
