which type of material would be most suitable?

hello,

i have created a device which would allow a fluid(A)to go into a chamber but allow fluid(B) to come out of a different chamber, at different times, using the same opening but not mixing. the fluid(B) is removed by using suction. there is two valves, the one leading to the opening of the fluid(A) going in is always open until the pressure is applied, closing it, opening the other chamber and allowing fluid(B) out. the diameter of each chamber opening is 5-10mm Does anyone know of a material which would be most suitable possibly an elastomer?

the surrounding material is likely to be an acrylic and would be made using injection moulding.

vicky.

Practically any valves would work base on the description provided here. I don't think that you've told us enough about what limitations or challenges you are facing. Why can't you just stick two valves in it?

What are fluid A and B? How precise should the Valves work? How long? What are the velocities of the fluids? What is the viscosity of A and B? What are the expected accolarations? Are the fluids adgesives? what are the temperatures?

perhaps PU solves your problem, perhaps you need FFKM (Kalrez)...

You are in the UK? perhaps you ask the guys of ceetak, perhaps the guys of James Walker or Hallite

if there is no problem with a strong german accent ask the guys of Parker Seal Group Europe (Packing Division) or Freudenberg or Busak & Shamban (ok, they normaly will tell you that you need PTFE) or Kaco..

but all of them need more informations

or just send an e-mail

The device is to help eliminate the opportunities for someone to drug a drink. Fluid A is a drug in powder, liquid or tablet form Fluid B is alcohol, mixer etc. The suction is the action taken by the drinker when taking a drink. The device would only be used once and then either disposed of either fully or partly biodegradable, recyclable or sterilised.

use a good EPDM or if You want to dispose it and want to use "political correct" biodegenerable material which is made of renewable source use Parker Ultrathan P5500 or P5501 ("non polar Polyurethan")
