HYDRAULIC FEATURES
Bells water hammer damper is design to attenuate transient flow known as “water hammer”phenomenon which is created in a closed conduit when there is an abrupt variation of the fluid velocity. This phenomenon presents itself when there is quick sequence of pressure excesses and drops which creates instability and generates noise and which can provoke serious damages to the systems and the connected devices. The water hammer damper must be installed near to the devices which can trigger this event such as ball valves, solenoid valves, mixing valves and all hydraulic components capable causing a sudden stoppage of the water flow in the pipelines. The norm UNI 9182 Ïnstallations for the alimentation and distribution of cold and hot water.
