Hi,
I was wondering if anyone knows a manuafacturer who makes an adjustable metering valve with manual bypass.
I want to be able to meter 100% o2 at a flow rate between 0.5 and 2.5 litres per minute, adjustable, but also have the option of pressing a manual bypass to inject 100% o2.
The valve would need to work upto 20bar inlet pressure, be o2 clean (obviously) and ideally fit into the palm of your hand.
Any ideas?
Many Thanks Wills.
