  • What is a Two Piece Stainless Steel Ball Valve?

    A Two Piece Stainless Steel Ball Valve is made of two 316 Stainless Steel Body Pieces that house the rotating ball inside it. These are two way units with a female port at either end. The Ball Valve is operated by rotating the Stainless Steel Handle 90 degrees which will open or close the ball valve. The handle is stopped at these positions by a limit stop which is cast into the body of the valve, this will stop the user moving the ball past the fully closed and fully open point.

  • How does a Two Piece Stainless Steel Ball Valve Work?

    Housed within the body of the ball valve is a polished 316 Stainless Steel Ball. This has a hole at either end which is equal to the inside diameter of the valve. When rotated 90 degrees it will either expose these holes to the flow or close them off from the flow allowing the valve to close or open. The ball is turned by a shaft which connects to a handle on the top of the valve. This type of Ball Valve is often called a floating ball valve as the ball itself is suspended within the cavity of the ball valve with the PTFE seats holding the ball from either end of the valve (and also sealing it).

  • What are Typical Uses of a Two Piece Stainless Steel Ball Valve?

    These two piece Stainless Steel Ball Valves are commonly used as an isolation valve. As they are watermark approved they are also used on a lot of potable water applications such as isolating water feeds and fire systems. Really they can be used in any application where the media, temperature and pressure fit within the scope of the ball valve. As they are all made of 316 Stainless Steel including the handle (many valves only have plated steel handles) they are also used frequently in corrosive environments.

  • How do I install a Two Piece Stainless Steel Ball Valve?

    These are very easy to install as they are bi-directional meaning they do not have a direction of flow (unlike a solenoid valve for instance). This model has female threaded ends so a male nipple or thread will need to be inserted into the valve. Ensure that this has appropriate thread sealant or tape to achieve a bubble tight seal. They can be installed on any axis and any way if needed.

  • How long will my Two Piece Stainless Steel Ball Valve Last?

    This really depends upon the environment and media that the ball valve is exposed to. The cycle rate will feature heavily as well as if the valve is only cycled once a day it may well last over a decade however if it is cycled frequently it will wear out sooner. We lab test these to 30,000 cycles and they still hold a bubble tight seal.

  • 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 API598 are available) and inspected so there are rarely any issues. Also once your valve is in and operating it will most likely continue to do so for a very long time.
