GA Industries Figures 624-D, 625-D and 626-D direct acting, spring loaded surge relief valves protect sewage and wastewater systems from excessively high pressure due to a sudden stoppage of pumping or valve closure.
The valves remain closed when the pressure at its inlet is below the spring setting but open as quickly as needed to discharge fluid out of the system at the rate necessary to prevent an excessive rise in pressure.The valve closes slowly and seals tightly when pressure decreases below the setting.
The valve’s streamlined, flow efficient, non-clogging long radius elbow or wye body provides dependable surge protection even when handling solids-laden fluids such as raw sewage.
