148B6037

The 148B6037 check valve belongs to the CHV Check Valves series from Danfoss and is intended to maintain one-directional flow in hydraulic automation circuits. It follows an angleway layout so the line changes direction at the valve body, saving space in tight pipe runs. Steel is used for the connection material to provide durability under high pressure and temperature cycling. The connection size is 100 mm, and the butt-weld connection type allows a permanent joint that resists vibration. The ends comply with ASME B36.10M Schedule 40 dimensions so installers can align it with standard process pipe without extra adapters. A Cv value of 232 gal/min indicates the volumetric flow the valve can pass when fully open, supporting high-capacity hydraulic loops.

The valve has a Kv value of 196 m³/h, giving the metric flow coefficient needed for sizing in European-based calculations. It withstands a maximum working pressure of 52 bar, enabling operation in medium-pressure oil or refrigerant circuits. Service temperatures from –60 to +150 °C permit use with cold-storage refrigerants as well as hot hydraulic oils. The disc lifts at a minimum differential pressure of 0.04 bar, so very small pressure imbalances are enough to open the passage and reduce pumping losses. Net weight is 14.102 kg, which installers must account for when selecting pipe supports and handling equipment during maintenance. This moderate mass also simplifies shipping and field replacement tasks.
