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 Release Valves function to release air pockets that collect at each high point of a full pressured pipeline. Air Release Valves can open against internal pressure, because the internal lever mechanism multiplies the float force to be greater than the internal pressure. This greater force opens the orifice whenever air pockets collect in the valve. Air Release Valves are essential for pipeline efficiency and water hammer protection.  Features:A streamlined disc profile provides smooth flow and ensures low pressure drop which is designed for strength and deflection eliminates possibility of flutter.   Specifications:   Size: 15mm to 200 mm Specification: General manufacturing standard, IS: 14845/G&K/AWWA: C-512 Application: Water, Stem Hot Water etc. MOC: CI/CS/SS/DI etc.

Specifications : Critical Tolerance : 0.017mm Weight : 24kg

  We are amongst the top companies involved in offering a wide range of Air Valve. These are manufactured using fine material which is procured from the reliable vendors of the market. These are highly reckoned among our clients due to their high strength and rigid construction. Additionally, these are necessary for pipeline efficiency and water hammer protection.

These valves are primarily used to remove air from Pipe Line when initially they are charged with water or fluids. It also helps in removing any trapped air during the operations.   When pipe lines are discharged with water or fluids it release air in the pipe line for quicker discharge of fluid to empty the line.   Type of Valves: Single Ball/Double Ball/Kinetic. Operation: Automatic.
