Join Bermad Water Technologies Air Valve and Product Manager, Colin Kirkland, in this technical training seminar on UL listed deluge control valves for use in Australian Road tunnels. In this presentation, learn more about:

  • Tunnel design challenges
  • Objective of deluge spray system
  • Typical tunnel designs
  • Importance of the deluge valves
  • Engineer challenges of the deluge valves
  • Bermad fire deluge valve range
  • Bermad’s history of Australian tunnel deluge systems


Hello, and welcome to another technical video seminar by Bermad Water Technologies. My name is Colin Kirkland and I’m one of the engineers at Bermad. The purpose of this presentation is to talk about fire suppression deluge valves and their inclusion in Australian tunnels under fire protection. The video is really focused at engineers or anyone within the fire industry designing, operating, or using deluge valves within any tunnel designs, which are being incorporated in fire systems. With that being said, let’s get into the content.

One of the first things we really want to talk about before discussing the valves in detail are tunnel designs and challenges. The tunnels which have been used in Australia have changed over a variety of years due to their length and complexity. And we’ll talk a little bit about some of the challenges which designers have when incorporating some of these valves and will go into it in a little bit of depth.

We’ll talk a little bit about the deluge valve itself. So what is it? How does it operate? What is it’s function? What are some of the challenges and what are some of the engineering concepts, which are really important when considering the inclusion of it, the sizing of it, and how it’s going to operate. And we’ll talk about some of those challenges as well.

We’ll specifically talk about three different types of Bermad deluge valves. We have what we call the 400E, which is one of the original valves, which we’ve had. We’ll then talk about the model 700E, which is another model with a similar sort of functionality, and also the 400Y, which is our new torrent valve, where it’s being used highly in a lot of the more frequent tunnels that are around today.

We’re also going to give you a little bit of an overview of some of the history of where we’ve used valves in Australia before. We’re going to show you some of the technical reasons why some of these valves were used, and some of the hydraulic conditions that we’re operating in, so that if you are looking at a tunnel design today, you can see, well, this has been done in the past. You can see they’ve got history and you can see that the flows and demands of their valve are achievable. And they’re actually being used presently in this format.
