The CVS type copper check valve is installed in the compressor discharge line to prevent condensed liquid refrigerant from flowing back into the compressor.
CVS type copper diaphragm check valve adopts a fully sealed valve body made of copper tube, integrated with filter screen, magnetic actuation and PTFE-coated diaphragm self-priming structure. This design ensures the automatic closing of the check valve is unaffected by installation angle and back pressure magnitude. It features extremely low flow resistance, high flow capacity, and nearly zero reverse leakage.
