Ordinary spring loaded pressure relieve valves which open at a predetermined pressure are of no use in relieving the high surge pressures encountered during in Water Hammer. The main reasons are that they are extremely slow in opening and they close down when they encounter a negative pressure. The Water Hammer surge consists of a series of quickly alternating waves of very high pressure and low pressure. To counter the Water Hammer surge what we need is a valve that opens quickly and sucks in air into the pipeline but does not allow this air to escape on encountering a positive pressure wave. The slow closing ensures that the subsequent positive pressure waves are damped by the action of the entrapped air.  In our Air Cushion Valve, the quick opening is achieved by a spring loaded air inlet port. The spring is designed to open at a preset pressure differential. The slow closing is achieved by using an orifice to expel the air at a controlled pressure and rate. The orifice effectively behaves like a pneumatic damper. By adjusting the setting of the orifice, we can control the outflow rate of air from the valve. All moving parts (shafts, bushes and stoppers) and the entire needle orifice are made of Stainless Steel. The rest of the body is a modular mild steel fabrication. The modular design allows for easy maintenance.The sizes of ACV valves depend on the pipe diameters in the following manner:ACV - 100 : up to 300 mm. pipe dia.ACV - 150 : From 300 to 400 mm. dia.ACV - 200 : Above 450 mm. dia.

Air Cushion Valve is a device to prevent collapse of pipe as well as bursting during sudden stoppage of pump or valve etc. It eliminates the chances of water hammer. Air Cushion Valve is provided with separate Inlet and Outlets for air. When a pumping machine stops suddenly, the water column travels forward due to its momentum. When the momentum is lost, it returns backwards and exerts a pressure at pump/valve. When the water column returns, it creates excessive pressure, which is the cause of water hammer. During this process, water column separates at various places creating vacuum. Air is required to fill the vacuum to prevent the pipe from collapsing in case of excess vacuum. Air Cushion Valves inhales the sufficient air at the time when water column separation takes place. Once the air is taken in and the water column starts returning, the air inlet is closed. Air is then compressed in between separated water columns. When air compression creates sufficient pressure, Outlet Valve opens, allowing air to escape under pressure. The outlet is further controlled by orifice controlled needle valve to limit the quantity of outgoing air. Thus the energy of water column is lost in expelling the air and an air cushion is formed in between the separated water columns. Due to this process the rejoining of water columns is very slow and increase in pressure at this moment is moderate.
