OK. Looks great mate.
When you say others available and mention part numbers, is there something I can look at with specs? Catalog maybe? You didn't mention your business / further contact info in your post.
Thanks,
Cheers.
Andy,
The safety valve I sourced was 15psi, and rated for steam, for about $30US
The pressure switch I sourced was also about $30 US and adjustable.
I would use it just under 15psi to turn an element on/off, but not pop the safety valve repeatedly. Being adjustable allows to test the pop valve occasionally, by upping the setting.
It was rated for 10amps from memory, so would allow a powerful element - though I think I'll be using less powerful.
Also sourced a pressure guage for about $10.
One problem with the US gear though, it is not BSP - though 1/2 NPT fits BSP, so adapters would be necessary.
I hope Roota responds, would like to see what he has that would fit the bill.
However, I would be grateful to take advantage of your US friend if necessary.
Cheeers.
Cheers.
