Industrial Valves

We provide premium quality of water hammer control devices that is used for controlling water hammer pressure. Water column separation and rejoinder are the main principles on which it works.

Water hammer control devices can be handling properly by using zero velocity valves & air cushion valves in pipelines that are placed in the pipeline carefully to ensure:

• Safe pipeline to face the vacuum & high pressure limits.
• Regulate the oscillations of water columns
• Decrease wear & tear and erosion of pipeline
• Manage C value of the pipeline for a long span
• Increase the life time of pipeline, valves & pumping machinery.
• Avoid leakages in the pipeline

The principle of the Air Cushion Valve is to allow large quantities of air in the

Pipeline during column separation occurring after pump tripping. It helps to avoid

Vacuum creation & thereby damage of the pipeline.

 

After column separation, when column start returning, the air entrapped inside is compressed, which provides cushioning effect, and expelled under controlled pressure so as to dissipate the energy of the returning water column. Delta Air Cushion Valves is tailor made valve, designed to suit the particular piping systems. The valve is designed from the data obtained from the computerized  surge analysis of the pipeline.
