Motorised Ball Valve

Two questions about motorised ball valves. Firstly - is there any guidance on when the 1/2" BSP verions might be available from the BrewPi store again? Secondly - I noticed that Tonhe list a tri-clamp version of what appears to be the same valve (ie with feedback limit switches). Does anyone know if this is available in small quantities (15 to 20) anywhere and / or is it an option that BrewPi store might consider listing?
Many thanks for any input, Andy
