Description:
1. CV type check valve is often used on the liquid, suction and hot air pipes of freezing, refrigeration and air conditioning equipment.
2. Made of high‑quality brass material, has high hardness, can withstand hot and cold pressure, and is suitable for various environments.
3. The one‑way valve is welded connection, and the valve base and the connection have good sealing performance.
4. Can prevent the refrigerant from flowing back from the high‑temperature evaporator to the low‑temperature evaporator, and can be used in a refrigeration device with parallel compressors.
5. The size of the check valve is standard, and the air tightness is good after installation, and it is not easy to cause air leakage.

Note:
1. When installing a check valve, pay special attention to the flow direction of the medium. The normal flow direction of the medium must be consistent with the direction of the arrow indicated on the valve body, otherwise the normal flow of the medium will be blocked. The bottom valve should be installed at the bottom of the pump suction line.2. When the check valve is closed, water hammer pressure will be generated in the pipeline. In severe cases, it will cause damage to the valve, pipeline or equipment. Especially for large‑mouth pipelines or high‑pressure pipelines, it should cause the check valve selection High attention.3. The check valve is only a one‑way opening and closing valve that prevents the backflow of fluid media on various pipelines or equipment.
