The System is managed through a control valve type XLC 312/412 including sectioning gate valves and by-pass for maintenance as well as a filter to prevent dirt from reaching the control valve. The control valve manages the upstream and downstream pressure in the System. The direct acting pressure sustaining VSM and reducer VRCD are the best choice for the by-pass line thanks to their reliability also after long periods of inactivity. Anti-surge combination air valves FOX 3F AS are recommended upstream and downstream as well as an additional pressure relief valve VSM to prevent rise in pressure on the line. We are providing all system components for a fast and reliable installation at the plant in accordance with the dimensions engineered by our technical department.
