Features:
Size 1/2" to 4" BSP
Body 316 Stainless Steel 3 piece
Seat PTFE + 50% SS316
Pressure 63 BAR
Temperature -20°C to 220°C
Actuation Heavy Duty Lever or Gear Box
High performance 3 piece full bore 316 Stainless Steel ball valve with BSP threaded connections and PTFE + 50% SS316 seats and a FFKM oring for temperatures up to 220°C. This valve features a self adjusting stem packing assembly with belleville spring for temperature fluctuations and vibration. The pre drilled metric hole on ISO5211 direct mounting pad minimises any thermal transfer from valve to actuator. This features a heavy duty lockable handle which allows for the handle to be locked in one position if required. It does not have a sliding tab like other lockable handles as these are usually used in high temperature applications where contact time with the handle should be minimal. Suitable for applications where a higher temperature demand exists that is outside the capability of a standard RPTFE Ball valve. Length to DIN3202-M3, Threads to ISO7/1 and mounting pad to ISO5211.

What is a High Temperature Stainless Steel Ball Valve?
These High Temperature Ball Valves are constructed of three separate body pieces and held together by the use of stainless steel tie rods with nuts at either end. This kind of design makes it easy to remove the valve from a line as you do not need to unscrew the ends from the pipework to maintain the valve. It is also very easy to change the valve seats as you can access them directly when the ends are removed 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 50% 316 Stainless Steel filler. They also use a FFKM shaft Oring which has a higher fluorine content than FKM (better temperature and chemical resistance). This allows higher pressures and temperatures up to 220 degrees celsius making it suitable for steam applications (refer to the temperature vs pressure graph). We also have cast a specific heavy duty stainless steel one piece handle with no locking tab. This allows greater torque to be applied to the valve and no locking tab needs to be pulled back to operate which is very important when the valve is operating at higher temperature.
-
How does a High Temperature Two Way Stainless Steel Ball Valve work?
The high temperature 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 hole at either end 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 heavy duty handle 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 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).
-
How do I install my High Temperature Ball Valve?
These have female parallel BSP threaded ends so it is best to put a male tapered BSP fitting into the valve ends. Thread tape or a sealant should be used to help the seal and also if dissimilar metals are used it will reduce dissimilar metal corrosion. The tie rods can be undone if needed and the ends installed by themselves but this is usually unnecessary and you would have to measure the exact face to face before your installation.
-
How long will my High Temperature 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 a lot longer. If it is on a corrosive media and in a dry application with a high cycle rate the life will be much shorter. Being a 3 piece construction it is relatively easy to change the seats out when there wear which is the main perishable in the valve. These are available as spare parts in a repair kit.
-
What are typical uses of a High Temperature Stainless Steel ball valve?
These are mainly used on steam and thermal oil applications however any media that requires a valve to operate at a high temperature this could be applicable.
-
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.
