• What is a 2 Way V port ANSI 150 Flanged Stainless Steel Ball Valve?

  An ANSI 150 Flanged V port ball valve is constructed of two seperate body pieces and held together by the use of stainless steel tie bolts. This kind of design makes it easy to remove the valve from a line as you can unbolt the flanges to remove the valve. It is also very easy to change the valve seats as you can access them directly when the body is unbolted making them ideal for applications where the seat is worn regularly. Our design also has a longer neck to reduce thermal transfer and a direct mounting pad for mounting actuators without the use of a bracket and drive dog. They also have a reinforced teflon (PTFE) seat which is filled with a 15% glass filler. This allows higher pressures and temperatures up to 180 degrees celcius making it suitable for steam applications (refer to the temperature vs pressure graph). If a higher temperature is required these seats can be changed out to a 50% stainless steel seat if required. The ball itself has a 60 degree V port in it so it will not achieve a full flow like a typical full bore ball valve but it will allow a higher degree of flow control.

• How does an ANSI 150 Stainless Steel V port Ball Valve work?

  These V port ball valves work the same as any normal two way ball valve whereby the ball is rotated 90 degrees within the body of the valve which will either open or close the valve. The ball itself has a V port in it which the media will flow through when it is open. When the valve is closed these holes are blocked off to the flow effectively isolating the media either side of the valve. The ball is turned by a handle (or actuator) which is connected to a shaft which in turn is mated to the ball by a female slot. When it is operated by a handle (our handles are lockable) there is a stop pin which only allows you to operate the valve in a 90 degree turn (this will take you from open to close or vice versa). When it is operated by a gear box the gear box will hit its stop on the worm drive which will not let the ball rotate past 90 degrees.

• How long will my FLanged V port Stainless Steel Ball Valve last?

  Like any valve this depends upon the usage case of your ball valve, its environment, media and how many times it is cycled. For instance if it is on a clean media, in a clean environment and not cycled regularly the life will be decades. As it is a V port and mostly used for flow control quite often the ball is only partly open. This exposes the seat to the media more than a traditional ball valve so will wear at a higher rate. These are available as spare parts in a repair kit.

• How do I install a Flanged V port Stainless Steel Ball Valve?

  As this is an ANSI 150 flanged 2 way valve it will need to be fitted between two of the same flanges (ANSI 150 standard) in the pipework. Between the mated flanges will need to be a gasket to ensure a positive seal. The type of gasket will depend upon the media and temperature, for instance a water application may use EPDM or NBR whereas a steam application may use graphite or a spiral wound gasket. The bolts should be fitted and then tightened in a diagonal direction to ensure an even fastening force across the face of the flange (for bolt torque refer to the flange standard).

• What are typical uses of a Flanged V port Stainless Steel ball valve?

  These V port ball valves are usually only used where a degree of flow control is desired. Examples include flow regulation in steam systems, water systems and any other application where the media, temperature and pressure is compatible.

• 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.
