Check Valve Brass Non Return 1 Way 1 2in Threaded Pneumatic Air Compressor Accessories

Feature: 1. Check valve is used to prevent reverse flow in hydraulic systems, or to prevent reverse flow of compressed air in pneumatic systems. 2. 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. 3. Made of high‑quality brass material, has high hardness, is not easy to deform, and has a high safety factor. 4. Prevent the refrigerant from flowing back from the high‑temperature evaporator to the low‑temperature evaporator, which can be used in the refrigeration device with parallel compressors. 5. The valve body is uniformly stressed, does not slip during installation, and is explosion‑proof and pressure‑resistant. Specification: Item Type: Check Valve Material: Brass Model: CV 12 Purpose: Prevent the refrigerant from flowing backward Structure: Spring type Connection Form: Screw connection Applicable Medium: Refrigerant Pressure Environment: High pressure Flow Direction: One way Drive Mode: Pneumatic Hex S: Approx. 24mm 0.9in A: Approx. 68.5mm 2.7in B: Approx. 18mm 0.7in Thread: 1 2in. Package List: 1 x Check Valve 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.
