Rotary snubber DALB series

hydraulicstainless steelforged steel

Large Bore Snubbers (DALB) are used for high load charge, more than 600 kN. Used for conventional or nuclear applications. Qualified for nuclear applications, used for steam generator and large pumps, in primary loop of nuclear power plants. Special fabrication on demand. Forged stainless steel rod with chemical nickel coating or chrominium. Forged steel for body and internal parts. Dynamic characteristics at ambient temperature, 15°C to 35°C Hereofter standard values, (others available on demand) FN is the Nominal load of the snubber • Drag force at slow speed, before locking : < 40 kN (DA12) • Lockup velocity : 6 mm/min < LV < 60 mm/min • Drift speed after locking : < 10 mm/min under maximum load • Lost motion : 1200 kN/mm under maximum load (DA12) • Theoretic stiffness in compression : > 1500 kN/mm under maximum load (DA12) • Functional temperature : 10°C to 60°C
