The 148B5294 valve belongs to the CHV Check Valves series manufactured by Danfoss for hydraulic automation circuits where reverse flow must be prevented. It uses a butt-weld connection sized at 15 mm that follows the EN 10220 pipe standard, allowing direct welding to matching lines. The connection material is stainless steel, giving the assembly consistent metallurgy from pipe to body. An angleway configuration turns the passage through 90 degrees so the component can fit tight piping layouts. An embossed one-way arrow on the housing serves as a flow indicator to guide correct installation. The valve begins to lift at a minimum differential pressure of 0.04 bar, ensuring early response in low-pressure systems.
Classified as a check valve, the unit tolerates working pressures up to 52 bar for medium-pressure duties covering fluid group 1 or 2. Its capacity is defined by a Cv of 9.3 gal/min and a Kv of 8 m³/h, providing sizing data in both imperial and metric terms. Service temperatures can range from –60 °C to 150 °C, which accommodates deep-cold or moderately hot process streams. A net weight of 1.31 kg reduces line loading while still offering sturdy construction for field installation.
