This Differential Pressure Control is managed through an automatic valve XLC 395/495 used for pump control, to avoid overload and cavitation, where pressure is taken before and after the pump in order to maintain the required difference in pressure. In case of by-pass, needed for maintenance, the pressure sustaining valve VSM is the best choice thanks to its reliability also after long periods of inactivity. Anti-surge combination air
valves FOX 3F AS are recommended upstream and downstream of the installation. 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.
