I'm designing a product that has a need for an inexpensive low pressure (<20psi) 9-way valve with orifices in the 1/8" range. This doesn't seem to exist on the market, and custom brass bodied valves blow our budget.
Something we are considering is making the valve body out of delrin with a central reamed hole and 8 smaller holes radiating out from it. Into that hole we'll press a stainless steel shaft with a coaxial hole and a single radial hole that can be rotated to align with the radial holes of the valve body.
The press will have to be light to allow the shaft to rotate under hand pressure, but still tight enough to form a good seal. The materials we are flowing are non abrasive and the valve will be cycled on the order of 50k times in it's expected life. Quantities will be ~5k.
Does this seem like a sane route to take? Is there an industry out there that regularly uses valves like these?
