Water transmission
The movement of water from various storage facilities to a given distribution networks, happens through water transmission pipelines. Pressure to move the water is created by the use of pumping stations at various points in the network or in some case through gravity. The water is transported from the source, to water treatment plants and then subsequently pumped into various kinds of reservoirs and distribution networks, which supplies water to private homes, companies and other users.
The type of pipes used in transmission various from country to country. Different varieties includes ductile iron pipes, steel pipes, concrete pipes or GRP/GRE pipes. For smaller pipelines plastic pipes might be used, such as HDPE. Different transmission networks have different types of valves installed. These valves different in specifications and features, but may at times serve the same purpose. The reason for this is that some designers might prefer the benefits associated with one valve over another.
The choice of valve may depend on project specification as well as different PN ratings, also known as pressure classes. For water transmission, AVK offers a wide range of different valves, made for different purposes, with different features and benefits. These valves include: concentric and double eccentric butterfly valves, gate valves, air valves, recoil check valves and swing check valves. In addition to this, AVK also offers related equipment and products such as couplings, repair clamps, handwheels, stem caps, gearboxes and so on.
