Brand Aqua Air Cushion Valves, Model NameNumber Float valve

The foundation of this air cushion the role of valves is to allow large quantities of airflow inside the pumping main during separation, Entrap the air, Compressed it with the returning air column and Force the air out under controlled pressure for the purpose of dissipate the energy for the ones who return water column. An air cushion valve is thus provided. The valve mounted on tee joint on the rising main at locations where water column separation is likely. The valve has a spring-operated air entry system port, An outlet normally closed a spring, By float loaded outlet poppet valve and an adjustable middle valve control orifice. When there is sudden stoppage of pump due to power failure, Partial vacuum is created in the main. With deferential pressure, The spring, Loaded port opens and admits outside infuse air into the main. When tension inside the main becomes near atmospheric. The inlet valve closes under spring pressure. The entrapped air is than compressed by returning water column till the poppet valve opens with float is the air, Dropped position is expelled through poppet valve and controlled orifice under predetermined pressure thus dissipating the energy of the returning water column.
