hi, this post (as well as my other posts) all relate to one project, and whilst the parts are coming together i seem to have hit yet another hurdle, but this one is really specific!
on my quest, i require a way of dispensing 25ml of liquid (1 bar, water density), in approximately half a second.
also, i don't have a never ending budget, so i have scoured high and low for low cost, but good products. i came across a 2 way (not required to be 2 way, but better pricing than 1 way, and it won't cause an issue) solenoid valve from Invensys (RS Component 342-023) and at £13 is a bargain (seeing as the usual price for these items seems to be £80-£150+
now, the specs say;
is this an amp issue? more current, more flow? has anyone worked with these (or similar items) before?
thanks

my issue / query is that although im chucking 12vdc through this thing, it doesn't flow more than the absolute minimum, and the item only has 2 contacts and no adjustable parts.Diaphragm operated, normally closed solenoid valves for controlling water at a minimum pressure of 0.2 bar
Coil can be located in any one of eight positions
Maximum flow rate: 0.25 to 17 litres per minute
0.2 to 10 bar pressure range
Power consumption: 4W
Nylon 6 body with 1/2 in. BSP ports (may be base mounted)
1/4 in. spade coil terminals
is this an amp issue? more current, more flow? has anyone worked with these (or similar items) before?
thanks
