Diaphragm check valve adopts magnetic diaphragm design and is mainly used in refrigeration units, commercial cabinets or small central air conditioners and refrigeration equipment. It can be applied to the discharge side and suction side of compressors in high temperature and high pressure parts; the interna guide design makes the check valve not limited by the installation angle; the function of the check valve is to control the one-way flow of refrigerant and prevent backflow.
Film-coated valve adopts flexible sealing, leakage in the reverse direction is negligible.
Minimal flow resistance, pressure loss is negligible.
Straight line, small size, light weight, unlimited installation angle.
A filter is installed in the valve body, with both function of check valve and filter.
Compatible with allfluorinated refrigerant and oil.
