The 148F3210 safety relief valve belongs to the SFA Safety Relief Valves series and is manufactured by Danfoss for hydraulic automation systems that need dependable over-pressure protection. It uses a G connection type so standard parallel threads can be applied during assembly. A 3/4 in inlet connection mates with common supply lines, and a 1 in outlet directs released fluid with limited back pressure. The spring is calibrated to open at 10 bar; when that limit is reached the mechanism lifts 4.8 mm, exposing a 13 mm flow diameter. This opening yields a 133 mm² flow area, allowing rapid discharge to prevent equipment damage. The valve is categorized in Fluid Group 1, indicating suitability for hazardous hydraulic media typically found in industrial installations.
Operating temperatures range from −50 °C to 100 °C, so the 148F3210 remains functional during cold starts and while handling warm return oil without loss of sealing performance. The internal volume of 1.342 L helps stabilize flow as pressure is relieved, reducing turbulence at the outlet. A net weight of 1.926 kg simplifies manual handling, while a gross weight of 1.968 kg defines shipping mass for logistical planning. These physical figures, combined with the wide temperature window, support reliable mounting near actuators or reservoirs where thermal cycles and vibration are present, completing the technical profile of this relief valve.
