Available in wafer, lugged and flanged (contact us for triple offset, double flanged or other variations). All are available with manual, electric or pneumatic actuation (double acting or spring return).

Our selection of butterfly valves includes a wide variety of models, ranging from 50 mm to 2,400 mm in size. If you visit the individual butterfly valve product pages, you can select the exact sizes that you need, along with any other applicable options such as lug size and seat type. Once you have made your selections, the unit price for the valve in question will be displayed, and you can add the required quantity to your cart.

As process industry specialists with decades of experience in Australia, you can be sure that any valves you order from us will be exactly as specified when they arrive at your site and will comply with all relevant Australia Standards.

Comprehensive butterfly valve range for all industrial applications

We stock a comprehensive range of butterfly valves, designed for use in mining, agricultural, irrigation, aquaculture, concrete batching, chemical, food processing, marine, oil, fire protection, pharmaceutical and general industrial applications. Whether you are looking for a manual, electric or pneumatic butterfly valve for an industrial application in Australia, you will find a model that meets your needs in our range. Datasheets for each valve can be viewed directly from our website, and you are more than welcome to contact us if you require any further technical information on any of the valves that we carry.

Advantages of butterfly valve design

Butterfly valves are the preferred option for many different industrial processes, owing to the advantages that this type of valve design has to offer. If you need a precise, fast-acting, low maintenance valve that can be actuated electrically, manually or pneumatically, a butterfly valve is often the most practical solution.

  • Lightweight and compact — The lighter weight and smaller footprint of butterfly valves (when compared to ball valves) make them an attractive option when space is at a premium and for applications where overall weight is a prime concern.
  • Ease of maintenance — The simple design, with few moving parts, makes a butterfly valve very easy to maintain in comparison to other types of valves.
  • Economical — Because they are smaller, lighter and simpler than alternative valve designs, butterfly valves are the most economical choice for many different types of industrial applications.
  • Fast — Most butterfly valve designs are fast-acting, which means they can be opened and closed more quickly than other types of valves. For applications where a high degree of flow control is desired, this makes the butterfly valve a great choice.
  • Flexible — Butterfly valves can be used in a huge variety of applications, including underground process control applications, making them one of the most flexible types of valve currently available.
  • Capable of handling large flows — Because butterfly valves are capable of handling large fluid flows, they are especially popular for irrigation and water industry applications in Australia.

  • What is a Butterfly Valve?

    A butterfly valve is a valve that utilises a rotating disc inside its body cavity to open/close or regulate flow. These can come in varying designs but most commonly can be found in a center line formation then followed by double offset & triple offset configurations.

  • How does a Butterfly Valve work?

    A butterfly valve works by the shaft rotating 90 degrees which will take the position of the disc in the flow from open to close (or vice versa). When it is closed a seal will be formed between the disc and the seat effectively stopping the flow of the media. When it is opened again the disc comes away from the seat and when it is fully open sits side (smallest surface area facing) on to the direction of the upstream flow. This 90 degree turn can take place from different actuation options including a hand lever, gear box, pneumatic, electric & hydraulic.

  • How long will my Butterfly Valve last?

    Like any valve this depends upon the usage case of your butterfly valve, its environment, media and how many times it is cycled. For instance if it is on a clean wet media, in a clean environment and not cycled regularly the life will be decades. If it is on a corrosive media and in a dry application with a high cycle rate the life will be much shorter. It will also vary according to the type of butterfly valve design used. In some instances such as a metal seat triple offset butterfly valve they can have an increased life span due to the inherent design factors.

  • How do I install a Butterfly Valve?

    This depends upon the type of butterfly valve design used. They broadly fall into two categories; wafer & lugged (including double flanged in the lugged category). Both will need to be installed in a pipeline (or lugged can go on an outfall application) so bolts will need to be used to secure the valve into place. Most center line designs use the seat as an integral gasket but other designs a gasket may need to be added to the sealing face. From here if the valve is actuated this will need to be hooked up and the valve should be tested in its open and closed position to check for leaks. For a full list of instructions please visit our butterfly valve installation & maintenance guide.

  • What are typical uses of a Butterfly Valve?

    These have a huge range of uses in industry today. They are usually found where larger sizes are used (say from 50mm and up) as under this size usually a ball valve would be used in its place. Anywhere where flow of a media needs to be isolated (or to a smaller extent regulated) you can usually find a butterfly valve.

  • How long will my product take to get to me?

    This depends upon where you are based and the freight method chosen. If the express freight option is selected it is usually next day delivery to metropolitan areas in Australia for under 5kg. If free freight has been selected it will go by road freight which can be anywhere from 1 to 10 days depending upon your location. It usually averages 3 days.

  • What warranty do I get?

    All of our products come standard with a 12 month warranty. The good news is we have very strict quality controls and all valves leave our warehouse tested (full material and testing certificates to API 598 are available) and inspected so there are rarely any issues.
