Suppliers of a range of air relief and double acting air relief/vacuum-breaker valves for pipelines.

The presence of air pockets and air-locks in pipe lines and pumping systems causes an enormous amount of trouble inrespect of efficiency and damage to equipment. It is essential to provide mechanisms to allow air to escape without affecting pipeline and/or pump performance. There is a dynamic relationship between pipeline diameter, operating pressure and the velocity of the liquid being conveyed.

Incorrect pipeline or pump design can cause pipelines to collapse and pumps to cavitate, causing expensive damage and downtime to plant and equipment.
