148B5336

The 148B5336 valve is part of the CHV Check Valves series manufactured by Danfoss for hydraulic automation systems where back-flow must be prevented. It directs media through an angleway flow path, which eases piping layout in tight installations. The butt-weld connection type matches a 20 mm pipe size under the EN 10220 standard, allowing direct integration with common industrial tubing. It can be installed in circuits carrying either fluid group 1 or fluid group 2 substances, broadening its application range. The design remains functional down to a minimum operating temperature of −60 °C, making it suitable for low-temperature process lines and refrigeration services.

A flow coefficient of 10 m³/h defines the capacity of the valve at a 1 bar pressure drop, supporting accurate line sizing. The body withstands a maximum working pressure of 52 bar so it can be used in high-pressure liquid or gas circuits. The internal spring and disc combination open once the differential pressure reaches 0.04 bar, which minimizes energy loss during normal forward flow. Operation is permitted up to 150 °C, covering many hot-oil or gas duties without material degradation. With a net weight of 1.28 kg, the component is light enough for quick installation while still providing robust service durability.
