The 148B5409 valve belongs to the SCA Check and Stop Valves series from Danfoss and serves hydraulic automation circuits by allowing directional flow and line isolation. It connects with a 25 mm butt-weld end made of steel, following ASME B 36.10M Schedule 80 pipe dimensions to ensure pressure-rated joints. The angleway body routes flow through a right-angle path to conserve space and limit pressure loss. Capacity is defined by a flow coefficient of 27.8 gal/min (Cv) and 24 m³/h (Kv), enabling accurate pump and line sizing. The unit begins to open at a differential of 0.04 bar, permitting quick response in low-pressure situations.
The valve handles fluids in groups 1 and 2 at working pressures up to 52 bar and temperatures from −60 °C to 150 °C, making it suitable for cold storage or high-temperature hydraulic oil. An internal volume of 8.931 L helps damp pressure transients, while a net weight of 3.486 kg and a gross weight of 4.173 kg support straightforward handling during installation. These physical figures let designers reserve accurate mounting space and lifting capacity. The combined pressure, temperature, and mass limits give the 148B5409 valve consistent performance when integrated into compact manifolds that demand precise flow control.
