In a wastewater management system, the transportation of the sewage and the wastewater is the most important process. As the population of humans grows, so does the waste produced by them. The gallons of wastewater and sewage that the pipes have to carry each day is not an easy task, and maintaining the pipes is the best way to make sure that the whole operation runs smoothly. Valves are the main accessory that can keep the pipes in proper functioning order and there are a lot of different valves that contractors must choose from. The Gate valves, Butterfly Valves, Ball type Valves are all used for isolation purposes however, the Air Release Valve is a sort of a safety valve that can control the amount of air pressure inside the pipelines.

For the proper functioning of pipes, the air present inside the pipes needs to be at a balance. Excess of air or lack of air can produce negative effects, and that is why we need a valve that can maintain the balance. Air Release Valves help during the intake of air, as well as by releasing the excess air. The pipes can be severely damaged if the air pressure is not optimized. Here are a few negative effects that can occur if there is a lack of air pressure or an excess of air pressure:

  • Excess air can decrease the flow rate of the liquid.
  • Excess air can create pressure variations in the pipe which can cause extra stress on the pipe.
  • Excess air can also give way to water hammer which can damage the pipes even more.
  • Lack of air in the pipes can cause negative pressure and damage the pipes because the water will be moving too fast.

There are three different types of air valves being supplied by Dutco Tennant, each with their own unique features. Some of the features are listed below to help you understand and differentiate between the three types:

  • Sewage Air Valves - This kind of Air Valve lets out a large amount of air during the time of filling or pumping, however, they admit the air back into the pipeline during a break or during drainage in order to avoid a vacuum in the pipes. This type of air valve closes when the sewer pipe is full of water and opens again only when the pressure in the pipe is lower than atmospheric pressure.
  • Vacuum Breaker Valve - Vacuum breaker valves are usually used to stop the backflow of water and prevent a vacuum within the pipes. These valves contain an air valve and a check valve. The check valve helps in stopping the back-siphonage as negative pressure causes backflow. The air valves on the other hand intakes air to negate the vacuum and stop the sophonage.
  • Combination Valve - Combination valves as the name suggests is a hybrid valve that has the properties of both the vacuum and air-release valves. These valves have an unique design that releases small pockets of air, when the pipes are full and working under pressure. To relieve negative pressures when water column separation occurs, this valve will open.

Since these valves are one of the most essential accessories required in a piping system, one should always buy them from a trusted supplier. Dutco Tennant is the best supplier of air valves and all types of valves that are required for wastewater management. We have been supplying industrial products for over 40 years in the Middle East and GCC region, and we have always put quality as our number one goal.
