EVDOS - Model PS - V Series - Pressure Sustaining Valve
PS - V valve maintains the upstream pressure constant in a defined point, regardless of pressure and flow - rate fluctuations. The pressure reducing pilot defines the desirable upstream pressure according to the regulation that have been made by a regulated bolt. Pilot regulates valve to open when upstream pressure reaches the required level and remains it constant. When pressure exceeds the preset level the sustaining pilot allows the valve to open fully.
