Join Bermad Water Technologies Air Valve and Product Manager, Colin Kirkland, in this technical training seminar on designing a pressure reducing station in water supply. In this presentation, learn more about:

  • Determining correct information to enable sizing of a station
  • The logic to determine size and number of valves required
  • Sizing reports and implementing in a design
  • Considerations for above or below ground installation
  • Installation techniques and pitfalls
  • Inlet strainers, air release valves and downstream pressure relief valves


Hi, welcome to this Bermad technical seminar. Colin Kirkland is my name I’m one of the engineers at Bermad water technologies. The purpose of this technical training seminar is we believe it’s going to be useful for any designers, operators, or engineers who are designing a pressure reducing station in water supply to share 30 odd years of experience, which we have in Australia of designing good and bad stations.

And to be able to go into many of the aspects, which might assist you in the design of a station.

So with that, let’s get started and get into the content which we’re going to provide here. One of the things that we found is really essential before designing a station is really to get the correct information to enable us as a manufacturer, to really design the right size of valve, the right station and the right sort of design.

So we’re going to talk a little bit about some of the information that we really think we need from you for to enable us to get that design done correctly. Once we’ve got a lot of that information, we’re going to talk a lot about the sizing logic that we use and why we use a single valve or multiple valves for that type of design.

And we’ll go into that in a little bit more detail. We’re going to show you some of the software which we use, which really takes out the risk of selecting that particular valve size. So, the software which biomed has, has had many years experience and really gives us a lot of confidence in what we’re going to do.

And we’ll share that with you and show you how we use that to as best band. sizing developers and with part of the solution. So part of the critical nature of any designers really thinking about, do we, how do we design the station? Do we put it above ground below ground? And we’ll talk a little bit about the pros and the cons, and this will maybe give you and help you in your selection process when you’re going into the actual detail of how the final design looks.

The thing that we found is really important is that designers, a lot of the time have a great idea of what they want, but this seminar is based on talking to operators, talking to people who do maintenance on the units, plus people who are designing. So all these different people have a different concept and what they think is useful and practical.

And then we’ll discuss some of the pitfalls relating to some of the main tech maintenance on the valve, because the, one of the critical things is, of course, it’s great to design it, but how are we going to work on. And is it practical to work on it in its present design? So we’ll talk a little bit about that too, as well.

We’ll talk about some of the components external to the actual valves, which have an impact on the performance of the pressure reducing station. One of the things we’ll talk about is do we need a strainer before the valve? Is it something that’s needed? Is it practical? And we’ll talk about the pros and cons of that.

When we design a station, one of the things that impacts the performance on the valve many times is air. And we don’t like air in any pressurized pipeline. So we’re going to talk a little bit about the design of the air valve we should suggest to use in particular designs and where to locate them and how to get the best performance out of that design too.

And also, there’s a, when you look at data catalog, sometimes you will see a pressure relief valve down stream; and we’ll talk a little bit about the pros and cons of using one of those and some of the design implications of putting one of those in a network.
