The 148F3232 safety relief valve is manufactured by Danfoss for the SFA Safety Relief Valves series. It protects hydraulic automation circuits by venting overpressure through an angleway body that turns flow ninety degrees. The valve uses external threads, and the thread form follows ISO 228-1 to match common pipe work. A G type connection is provided for standardized installation. The inlet measures 3/4 in, while the outlet is 1 in to reduce back-pressure on discharge. A 13 mm flow diameter sets the internal passage size needed for the rated capacity.
The valve opens to a 133 mm² flow area when actuated, ensuring rapid pressure relief. A lift of 4.8 mm controls the maximum travel of the sealing element and defines the discharge curve. Classification in fluid group 1 makes the unit suitable for hazardous liquids or gases found in industrial hydraulic systems. The assembly weighs 1.926 kg, which guides support and handling choices during installation. These operating values provide predictable relief behavior aligned with system safety requirements.
