A high pressure stainless steel ball valve is a two piece design where the body is made of two cast 316 stainless steel pieces which are threaded together and hydraulically locked. The wall thickness is usually much larger than a lower pressure ball valve as it can accomodate a much higher pressure range (ours will do up to 200 Bar). This design also features a ISO5211 direct mounting pad which can be unusual to find in a high pressure ball valve (this allows you to direct mount an actuator to the valve). The seats are Delrin which is great for high pressures but has a narrower range of compatible media when compared with PTFE which is typically used at lower pressures. They also come with a lockable stainless steel handle.

These high pressure 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 either end which the media will flow through when it is open (the ball is a solid ball so it can withstand the higher pressure). 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.

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. If it is on a corrosive media and in a dry application with a high cycle rate the life will be much shorter. We conduct regular lab testing and 10,000 cycles is a reasonable life cycle depending upon the application. 

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. As this is potentially working at higher pressures a firm seal needs to be achieved.

These are usually used in higher pressure applications (otherwise a normal 1000 WOG ball valve would be used) such as water blasting/spraying and chemical injection. Really anywhere where the media is compatible with delrin and stainless steel and the pressure is higher than what can be run in a standard ball valve.

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.

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.
