It’s a good rule of thumb (threaded):

In Australia, standard ball valve components are the housing, seats, ball, and lever used to rotate the ball. Two, three, and four-port valves are among the options, as valves are either female or male threaded (or both).

Hydraulic:

Hydraulic ball valves in Australia are ideal for hydraulic and heating systems because of their high working pressure and resistance to hydraulic and heating oil. Steel or stainless steel can be used to make these valves in Australia. Additionally, the seats of hydraulic valves are designed to withstand high working pressure. Polyoxymethylene (POM) seats are used in these valves to withstand high pressure and low temperatures. Hydraulic ball valves can withstand up to 500 bar pressures and temperatures of up to 80°C.

In that case, you may find a wide variety of options: with approval for certain media or applications, with a built-in strainer or bleed point or even with an integrated filter. Pressure and temperature ranges can be adjusted to suit the application’s needs.

Flanged:

In terms of connections, flanged ball valves in Australia stand out. Flanges are used to connect the ports to a pipe system, and these flanges are often built to meet a certain standard. Because of their full-bore design, these valves have a high flow rate. Flange compression class is another factor to consider when selecting a flanged ball valve since it shows the maximum pressure this connection type can tolerate. In Australia, these quarter-turn ball valves can be made with two, three, or four ports, authorised for specific media, and have an ISO-top, among other features. Stainless steel, steel, or cast iron are the most common materials used in their construction.

Vented:

When it comes to design, vented ball valves resemble standard 2-way ball valves. The critical distinction is that it vents to the outside environment when the outlet port is closed. A tiny hole is bored into the ball and the valve body to accomplish this. The pressure is released when the valve shuts and the holes align with the outflow port. As an example, depressurisation of compressed air systems creates a more secure working environment. They appear to be 2-way ball valves; however, they are 3/2-way because of the tiny venting holes.

To comprehend a ball valve, one must be familiar with the five major components of a ball valve and the two modes of operation. The valve’s stem is attached to the ball and can be controlled mechanically. The ball valve seat and o-rings on the valve stem support the ball. In the valve housing, everything is secure. A quarter-turn of the valve stem opens or closes the bore.

The purpose of a circuit may be summarised below:

Two, three, or even four ports may be available in a single valve (2-way, 3-way or 4-way). A lever-operated ball valve is the most common type on the Australian market today. When the valve is opened, the lever is aligned with the pipe. The handle will be perpendicular to the pipe when it is closed. The flow direction of a two-way valve’s ball valve is simply from input to output. Fast-moving media can cause water hammers if manual ball valves are closed too soon. Transmission is available on some ball valves. 3-way valves influence circuit performance (flow direction) with an L or T-shaped bore. A variety of circuit functions, such as distributing or mixing flows, can be accomplished due to this design.
